Cancer pain comes with the territory when you’re a cancer patient. For those who have advances stages of cancer or cancer that has spread through the body, cancer pain is inevitable. The thing about cancer pain is that it comes in waves and differing degrees. One day the pain might be nearly non-existent and you can go about your life as normal as possible, while the very next day could be excruciating. The first step is to understand the pain.

Understanding Cancer Pain

Cancer pain can be caused by many things; the cancer itself releasing chemicals into the body, the tumor pressuring the nerves, bones or other organs, or the cancer treatments such as chemotherapy, radiation and surgery. According to the Mayo Clinic, chemotherapy can cause many potentially painful side effects, including mouth sores, diarrhea and nerve damage. Radiation can leave behind a burning sensation or painful scars, and surgery recovery can be incredibly painful.

Tumors can also press on the spinal cord, creating a great deal of pain in the back and neck. These kinds of tumors create spinal cord compression, which ultimately can mean weakness in the entire body and pain in the arms and legs. Worst case scenarios of spinal cord compression can mean a loss of bladder or bowel control and paralysis.

Phantom pain is the toughest pain to control because it occurs after an arm, leg or breast has been removed. After the surgery to remove the cancer, many recovering patients will still feel pain or other unusual feelings that “seem to be coming from the absent (phantom) body part. Doctors are not sure why this happens, but phantom pain is real; it is not ‘all in your head,’” according to Cancer.org.

Persistent and Breakthrough Pain

When it comes to cancer pain management, there are two forms of pain that every cancer patient lives with; persistent pain and breakthrough pain. Persistent pain is just that; pain that is continuous and is controlled by regular pain treatment and visits to the cancer pain doctor. Breakthrough pain is those moments of extreme pain that ‘breakthrough’ no matter what type of treatment method you are undergoing. Breakthrough pain is unpredictable, sharp and quick, can last as long as an hour, and is incredibly intense.

Breakthrough pain is another fact of life for cancer patients. Even while your cancer pain management might be working wonderfully, breakthrough pain can strike without warning and take you out of life for the rest of the day. Occurrences of breakthrough pain do not necessarily mean your cancer pain treatment isn’t working, because many times this form of pain can ‘breakthrough’ all forms of effective treatment. However, if you are experiencing greater occurrences of breakthrough pain, consult your cancer pain doctor about other treatment methods.

The Pain caused by cancer usually falls into one of two categories:

Nociceptive Pain and Neuropathic Pain.

Nociceptive pain is caused by damage to tissue. It is usually described as sharp, aching, or throbbing pain. It is often due to tumours or cancer cells that are growing larger and crowding body parts near the cancer site. It may also be from cancer that has spread to the bones, muscles, or joints, or caused a blockage of an organ or blood vessels.

Neuropathic pain happens when there is actual nerve damage. It may be caused by a tumour pressing on a nerve or a group of nerves. People often describe this pain as a burning or heavy sensation, or numbness.

If you have been diagnosed with cancer pain, talk to your doctor to learn whether you may be a candidate for pain-control pump (intrathecal drug delivery). Your doctor (or a doctor to whom you are referred) will put you through a screening process to determine if these treatments may benefit you. Results vary; not every result is the same.

Key messages about cancer pain

The experience of pain will be different for every patient.

? Pain does not always get worse. The level of pain experienced may remain unchanged, or may increase or decrease. In any situation medication can be adjusted to ensure pain relief.

? Pain is not related to the extent of the cancer. Experiencing pain does not necessarily mean that the cancer is more serious than if you had no pain.

? Take action as soon as the pain starts. Take pain relief when you first start to feel uncomfortable. It is harder to ease pain once it has taken hold. Taking medication for pain relief when the pain is bearable will not make the medication less effective later. The aim is to prevent pain. If you wait until the pain comes back you will suffer from unnecessary pain.

? When pain relief is taken regularly or ‘by the clock’ (such as every 4 hours), there is little danger that you will become addicted to these drugs. Addiction to pain killers is very rare in women with metastatic breast cancer. The dose can be tailored to your needs. Doses are increased or decreased according to the severity of your pain.

? Drugs for pain do not usually make you feel drowsy after the first or second day. Drowsiness can occur with strong pain relief drugs like morphine. However, the drowsiness usually passes in one or two days. People vary in how the medication affects them. You should ask your general practitioner about whether you can drive or work with machinery, and the effect of drinking alcohol with your medication.

? If one drug does not effectively help your pain, many other drugs or combinations of drugs can be used to give you pain relief. There is a large range of effective drugs for pain of all types and severity. It may take time, in consultation with your doctor, to establish the drug or drug combination that is right for you.

? Any pain can be difficult to cope with. However, pain is more difficult to cope with if you are also experiencing anxiety or depression. Also, being in pain can make you more likely to be depressed or anxious. If you are concerned by the feelings you are experiencing, it is important that you talk to your doctor as soon as possible.

Why Do People Suffer With Pain?

Many people suffer with chronic pain because they are unaware of treatment options that can help them live more normal lives. Others have fears that prevent them from talking about their pain, which in turn creates barriers to seeking adequate relief. (Not all treatment options are applicable to your type of pain.)

Read the following to see if you fall into one of these categories. If you can relate to these fears, remember that help and relief are possible, but only if you discuss your symptoms with your doctor.

? Fear of being labelled a “bad patient.” You won’t find relief if you don’t talk with your doctor about your pain.

? Fear that increased pain may mean that your disease has worsened. Regardless of the state of your disease, the right treatment for pain may improve daily life for you and your family.

? Fear of addiction to drugs. Research shows that the chance of people with chronic pain becoming addicted to pain-relieving drugs is extremely small. When taken properly for pain, drugs can relieve pain without addiction. Needing to take medication to control your pain is not addiction.

? Lack of awareness about pain therapy options. Be honest about how your pain feels and how it affects your life. Ask your doctor about the pain therapy options available to you. Often, if one therapy isn’t effectively controlling your pain, another therapy can.

? Fear of being perceived as “weak.” Some people believe that living stoically with pain is a sign of strength, while seeking help often is considered negative or weak. This perception prevents them seeking the best treatment with available therapies.

Management of Pain and side effects

You may experience acute pain due to your illness or after surgery. You do not need to put up with this pain, your health care team can work with you to prevent or control just about any kind of pain. A combination of pain control methods may be used to give you greater relief from pain.

Don’t let pain control you! Because there are many new ways to treat pain, it is important that you speak openly and honestly with your doctor or with a doctor who specializes in treating chronic pain.

Understanding cancer pain Dr (Maj) Pankaj N Surange Introduction

When you or a loved one receives a diagnosis of cancer, it isn’t long before you begin to think of the pain many people associate with cancer. It can be a frightening time. What will the pain be like? What will it do to our lives? Many people with cancer eventually experience pain due to their condition. Approximately twenty percent of patients with newly diagnosed malignancies complain of pain. Thirty percent of patients undergoing cancer treatment complain of pain, and up to ninety percent of those with advanced cancer experience pain (Grossman 1994).
Pain associated with cancer can take many forms and is experienced differently by each patient. Pain can be sharp and severe, or it can be a dull constant ache. Regardless of the type of pain, a diagnosis of cancer does not mean you have to suffer with debilitating pain.
Today, most concerns about cancer-related pain can be relieved by understanding the facts about cancer pain, and learning about the help that is available for pain relief.

How pain happens?

Pain is transmitted through the body by the nervous system when our nerve endings detect damage to a part of the body. The nerves transmit the warning through defined nerve pathways to the brain, where the signals are interpreted as pain. Sometimes pain results when the nerve pathways themselves are injured. You feel pain when your brain receives the signal from your nerves that damage is occurring. All types of pain are transmitted this way, including cancer pain.
Pain can be acute or chronic: Acute pain usually starts suddenly, may be sharp, and often triggers visible bodily reactions such as sweating, an elevated blood pressure, and more. Acute pain is generally a signal of rapid-onset injury to the body, and it resolves when pain relief is given and/or the injury is treated.
Chronic pain lasts, and pain is considered chronic when it lasts beyond the normal time expected for an injury to heal or an illness to resolve. Chronic pain, sometimes called persistent pain, can be very stressful for both the body and the soul, and requires careful, ongoing attention to be appropriately treated.
Along with chronic cancer pain, sometimes people have acute flares of pain when not all pain is controlled by the medication or therapy. This pain, usually called breakthrough pain, can also be controlled by medications.
Cancer pain can be caused by many different sources. Pain can be experienced when a tumor presses on nerves or
expands inside a hollow organ. Pain also commonly originates from bone destructive lytic lesions. Bone marrow infiltration commonly cause bone pain that can be severe. Unfortunately, the radiation and chemotherapeutic treatments that are frequently used to treat cancer can also cause pain.
Assessment of your pain
The first step in getting your pain under control is talking honestly about it.
This means telling them:
• Where you have pain
• What it feels like (sharp, dull, throbbing, constant, burning, or shooting)
• How strong your pain is
• How long it lasts
• What lessens your pain or makes it worse
• When it happens (what time of day, what you’re doing, and what’s going on)
• If it gets in the way of daily activities
Your pain physician may ask you to describe your pain in a number of ways. A pain scale is the most common way. The scale uses the numbers 0 to 10, where 0 is no pain, and 10 is the worst. You can also use words to describe pain, like pinching, stinging, or aching. Some doctors show their patients a series of faces and ask them to point to the face that best describes how they feel.

Your Pain Control Plan

Only you know how much pain you have. Telling your doctor and nurse when you have pain is important. Not only is pain easier to treat when you first have it, but pain can be an early warning sign of the side effects of the cancer or the cancer treatment. You have a right to pain relief, and you should insist on it.
Cancer pain can almost always be relieved.
There are many different medicines and interventions available to control cancer pain. You should expect your doctor to seek all the information and resources necessary to make you as comfortable as possible. However, no one doctor can know everything about all medical problems. If you are in pain and your oncologist suggests no other options, ask to see a pain specialist or have your doctor consult with a pain specialist.
Controlling your cancer pain is part of the overall treatment for cancer.
Your pain physician wants and needs to hear about what works and what doesn’t work for your pain. Knowing about the pain will help your doctor better understand how the cancer and the treatment are affecting your body.
Preventing pain from starting or getting worse is the best way to control it.
Pain is best relieved when treated early. You may hear some people refer to this as “staying on top” of the pain. Do not try to hold off as long as possible between doses. Pain may get worse if you wait, and it may take longer, or require larger doses, for your medicine to give you relief.
You have a right to ask for pain relief.
Not everyone feels pain in the same way. There is no need to be “stoic” or “brave” if you have more pain than others with the same kind of cancer. In fact, as soon as you have any pain you should speak up.
People who take cancer pain medicines, as prescribed by the doctor, rarely become addicted to them.
Addiction is a common fear of people taking pain medicine. Such fear may prevent people from taking the medicine. Or it may cause family members to encourage you to “hold off” as long as possible between doses. Addiction is defined by many medical societies as uncontrollable drug craving, seeking, and use. When opioids (also known as narcotics) — the strongest pain relievers available — are taken for pain, they rarely cause addiction as defined here. When you are ready to stop taking opioids, your pain physician gradually lowers the amount of medicine you are taking. By the time you stop using it completely, the body has had time to adjust.

Treatment options

There is more than one way to treat pain. A simple, well-validated and effective method for assuring the rational titration of therapy for cancer pain has been devised by WHO. It has been shown to be effective in relieving pain for approximately 90 percent of patients with cancer and over 75 percent of cancer patients who are terminally ill. The World Health Organization (WHO) in 1986 established a stepladder approach for treatment of patients with cancer pain (fig.). The goal for this ladder was to provide treatment guidelines that healthcare practitioners could easily follow. The five essential concepts in the WHO approach to drug therapy of cancer pain are:
i) By the mouth. ii) By the clock. iii) By the ladder. iv) For the individual.
v) With attention to detail.
Medicines
Non opioids
Opioids
Adjuvants

Medicines are prescribed based on the kind of pain you have and how severe it is. In studies, these medicines have been shown to help control cancer pain. Doctors use three main groups of drugs for pain: nonopioids, opioids, and other types
1. Nonopioids – for mild to moderate pain
Nonopioids are drugs used to treat mild to moderate pain, fever, and swelling. On a scale of 0 to 10, a nonopioid may be used if you rate your pain from 1 to 4. These medicines are stronger than most people realize. In many cases, they are all you’ll need to relieve your pain. You just need to be sure to take them regularly.
You can buy most nonopioids without a prescription. But you still need to talk with your doctor before taking them. Some of them may have things added to them that you need to know about. And they do have side effects. Common ones, such as nausea, itching, or drowsiness, usually go away after a few days.
2. Opioids - for moderate to severe pain
If you’re having moderate to severe pain, your doctor may recommend that you take stronger drugs called opioids. Opioids are also known as narcotics. You must have a doctor’s prescription to take them. They are often taken with aspirin, ibuprofen, and acetaminophen. Getting relief with opioids
Over time, people who take opioids for pain sometimes find that they need to take larger doses to get relief. This is caused by more pain, the cancer getting worse, or medicine tolerance (see Medicine Tolerance and Addiction). When a medicine doesn’t give you enough pain relief, your doctor may increase the dose and how often you take it. He or she can also prescribe a stronger drug. Both methods are safe and effective under your doctor’s care. Do not increase the dose of medicine on your own.
3.Adjuvants
They can be used along with nonopioids and opioids. Some include:
Antidepressants. Some drugs can be used for more than one purpose. For example, antidepressants are used to treat depression, but they may also help relieve tingling and burning pain. Nerve damage from radiation, surgery, or chemotherapy can cause this type of pain.
Antiseizure medicines (anticonvulsants). Like antidepressants, anticonvulsants or antiseizure drugs can also be used to help control tingling or burning from nerve injury.
Steroids . Steroids are mainly used to treat pain caused by inflammation (swelling.)

Interventions

While opioids are the mainstay of cancer pain management, they have their limitations. Some patients may only tolerate moderate doses of opioids, manifesting side-effects such as sedation, confusion, and constipation. Another reason for opioid

Pain killers for dogs with cancer are often the smartest thing we will be able to do to help them. We don’t want our beloved dogs to suffer, so it is important to medicate them for pain when they have cancer. People diagnosed as having cancer always get pain medicine and treatment. Sometimes dogs with cancer get neither treatment nor pain medication. This is not because we don’t love our dogs, but for several reasons.

When reasons.

When dogs have clear mounds or cancers, folk sometimes make them to the vet. An aberrant swelling or pile is a standard sign of cancer. The vet will do a biopsy of the tissue to determine if it is benign or noxious. If benign, it might not be necessary to take away the cancer right away. A benign cancer is not likely to be painful for a dog, but can sometimes it can grow and be a problem. Benign growths can seriously constrict the dog’s movement or putt unhealthy pressure on urgent organs. At some point, surgery to remove a benign growth could be recommended by the vet.

When cancer tumors are evil, vets generally wish to operate and take away the malignancy before the malignancy spreads. The choice to continue with surgery for either benign or evil cancers could be awfully hard for you. Your beloved dog wants an operation, but you have to consider many issues.

Perhaps your dog is old and you worry about putting him or her through the physical and emotional stress of an operation. With benign growths, the chances for full recovery are good. With malignant growths, there’s always some probability that not all the evil cells will be removed and the tumor will reappear. That could be a difficult call, but you’ll have to make it. Whether or not you will need to get pain medicine for your dog. Malignancy is nearly bound to cause pain for your dog. While the benign cancer isn’t painful in the same way that the malignant tumor is, it can still cause pain.

Sometimes people just can’t afford to pay for the surgery. Occasionally the cancer is inoperable. Whether there’s surgery, you will want to make certain your dog does not suffer. Pain killers for dogs are affordable now and you need to confirm your dog gets medicine and does not suffer.

If the operation on malicious cancer is a failure and the tumor recurs in your dog, the vet may counsel chemical treatment or radiation therapy. Both of these treatments are just too expensive for plenty of us, much as we like our dogs. That’s when we need to focus our full attention on treating our dog’s pain.

It’s terrible to think about, but we do not need to go into denial and let our dogs’ final days be unhappy. When people are in the final stages of cancer, they regularly get hospital care to confirm they have enough pain medicine and loving care. Pain killers for dogs completely are crucial in the final stages of cancer. Dog lovers should guarantee that they give their dogs with cancer are also given love and pain killers at every part of cancer and especially at the final stages.
