Ignacio first noticed the signs of his non-Hodgkin lymphoma when he had trouble breathing and was coughing a lot during football practice. He also started having fever without knowing why. He told his parents, and they took him to the doctor. The doctor did an exam and ordered some lab tests and a CT scan. Everyone hoped that it would not show anything, but a lump was found. After some more tests, including a biopsy by the surgeon, the doctors diagnosed Ignacio with non-Hodgkin lymphoma.
At first, Ignacio was scared when he heard that non-Hodgkin lymphoma is a form of cancer. But he quickly learned that it's highly treatable, especially if caught early, as his was. Ignacio was relieved when his doctor told him that the odds were good that he'd be cured.
A lymphoma is a cancer of the lymphatic system. The lymphatic system is a part of the body's immune system and helps filter out bacteria, viruses, and other unwanted substances.
Most people don't notice the workings of their lymphatic systems; in fact, the only time you might be aware of your lymphatic system is when the lymph nodes (which are sometimes referred to as glands) swell up. This often happens when a person is sick — a sign that the lymphatic system is working hard to filter harmful substances out of the body.
Non-Hodgkin lymphoma is a disease in which cancer cells form in the lymphatic system and start to grow uncontrollably. There are several different types of lymphomas. Some involve a particular type of cell; these are grouped under the heading Hodgkin lymphoma. All other forms of lymphoma fall into the non-Hodgkin grouping. The different forms of non-Hodgkin lymphoma depend on such things as what the cells look like under a microscope.
No one really knows what causes non-Hodgkin lymphoma. Doctors have identified some risk factors (things that may increase a person's chances of developing a particular condition) for non-Hodgkin lymphoma. These include conditions that weaken the immune system, such as acquired immunodeficiency syndrome (AIDS), taking immune-suppressing medications following organ transplants, and exposure to certain viruses, such as Epstein-Barr virus (the virus that usually causes mono). Often, experts never find out exactly why a person gets lymphoma.
People who have a brother or sister who has had the disease are also more likely to get non-Hodgkin lymphoma. But, it's not contagious — you can't give it to someone and they can't catch it from you.
Of course, just because you've had mono or an organ transplant doesn't mean you'll get the disease: Most people with non-Hodgkin lymphoma don't have any of these risk factors.
The signs and symptoms of non-Hodgkin lymphoma vary from person to person depending on the type of lymphoma and where a tumor is located. Some people may feel stomach pain, constipation, and decreased appetite. Others may have trouble breathing, difficulty swallowing, and notice coughing, wheezing, or chest pain.
Other symptoms may include:
The symptom that some people notice first is swollen lymph nodes — usually in the neck, armpits, and groin. Of course, swollen lymph nodes do not usually mean cancer — they're most often a sign of a common illness, like an infection. In fact, all of the symptoms of non-Hodgkin lymphoma also can be caused by other conditions, which is why only a doctor can determine what's really wrong.
In addition to doing a physical examination, the doctor will ask you about any concerns and symptoms you have, your past health, your family's health, any medications you're taking, any allergies you may have, and other issues. This is called the medical history.
If your family doctor suspects non-Hodgkin lymphoma, he or she will refer you to an oncologist, a doctor who specializes in the treatment of cancer. The oncologist will then do tests to diagnose the problem.
If someone has swollen lymph nodes, the doctor may want to perform a biopsy if the swelling does not go down after other treatments. A biopsy is a type of test where a doctor removes a tiny bit of tissue from the body and sends it out to a laboratory for a specialist to examine. Depending on the type of biopsy a person has, a doctor may use local anesthesia (where only a part of the body is numbed) or general anesthesia (where a person is asleep) to ensure there's no pain.
Biopsies used to test for non-Hodgkin lymphoma include excisional biopsy (where the doctor opens the skin to remove an entire lymph node) or incisional biopsy (where the doctor removes only a part of the lymph node).
Another type of biopsy, fine needle aspiration (where a very thin needle suctions out a small amount of tissue from the lymph node) is used on some occasions to diagnose non-Hodgkin lymphoma. Doctors sometimes also perform a bone marrow biopsy, where a needle is used to take samples of the soft tissue found in a bone.
Your doctor may do other tests to diagnose non-Hodgkin lymphoma, including:
Once doctors have made a diagnosis of non-Hodgkin lymphoma, they use what's called a "staging system" to determine how much the disease has affected the body. Knowing the stage the disease is in helps the doctor decide on a form of treatment.
The most common treatment for non-Hodgkin lymphoma is chemotherapy. Chemotherapy is medicine that kills or stops the growth of cancer cells. Patients are also sometimes treated with radiation therapy.
For some patients who are receiving very aggressive chemo or radiation treatments, doctors may perform bone marrow or stem cell transplants to replace cells damaged by the treatment. These transplants involve using the cells from bone marrow or blood that has either been taken from the patient or has been donated by another person. These cells are then inserted into the patient's bloodstream to replace those that have been damaged or destroyed.
In a few special situations (such as high-risk patients or patients whose cancer has come back), doctors are using a new treatment called immunotherapy (or biological therapy). In immunotherapy, doctors use substances that occur naturally in the body to build someone's resistance to disease. Although they replicate naturally occurring substances, those used in immunotherapy are often manufactured in a laboratory.
If you've been diagnosed with non-Hodgkin lymphoma, you know how scary having the disease can be at times. There's a lot to deal with emotionally. Plus, appointments, tests, and treatment schedules can be tiring, and the treatments you have to get can make you feel lousy.
People who are being treated with chemotherapy or radiation can expect certain side effects. Most are temporary — although, as with all medical treatments, each person is unique and experiences side effects differently. The severity of side effects and how long they last depends on the individual and type of medicine and treatment that a doctor prescribes.
The most common short-term side effects of chemo are nausea and vomiting, but medicines given with chemo can prevent this in most people. Another common side effect is a lowering of blood counts, which can put people at risk for infection or bleeding.
Some people feel weak or dizzy after their treatments, or they run a fever. Others get sores in their mouths or suddenly don't feel much like eating. It's also common for patients to lose some or all of their hair.
The short-term side effects of radiation can be similar to those of chemotherapy, although they're usually more localized, meaning they affect only the area that receives the radiation treatment.
Some people feel side effects for weeks after their treatment ends. Tell your doctor if you experience any side effects of treatment. Your doctor also can discuss any long-term side effects of the type of treatment you are having.
If you have or have had non-Hodgkin lymphoma, it's important to see your doctor regularly for the years following treatment. Occasionally, cancer may return, and follow-up appointments with your cancer specialist can help you catch it early if it does. Also, your doctor will be watching for any late side effects of treatment.
Although non-Hodgkin lymphoma can be an aggressive disease, treatments have improved in recent years — and researchers are constantly developing new and improved approaches to curing the disease. Today, the percentage of people who are cured is about 70% or higher.
