What Is Lymphoma? Lymphoma is a group of cancers that begins in the lymphatic system. The function of the lymphatic system is to drain excess tissue fluid called lymph. The lymphatic system also contains blood cells known as lymphocytes, which are important in fighting infection. Lymphoma is the uncontrolled growth of lymphocytes.
What Are the Types of Lymphoma?
There are two types of lymphoma: Hodgkin’s and Non-Hodgkin’s Lymphoma.
Hodgkin’s Lymphoma is recognized by the presence of special cells that can be seen under the micros cope, called the Reed-Sternberg cell. Only 12.5% of all lymphomasare the Hodgkin’s type.
Non-Hodgkin’s Lymphoma is the most common type of lymphoma and is divided into many groups of lymphatic cancers. There are many different types of Non-Hodgkin’s Lymphoma.
What Are the Key Statistics About Lymphoma?
In the year 2015, about 80,900 people will be diagno sed with lymphoma. About 71,850 are expected to have the Non-Hodgkin’s type and about 9,050 for the Hodgkin’s type of lymphoma. Approximately 20,940 people will die of the disease this year.
What Are the Signs and Symptoms of Lymphoma?
A swelling of lymph nodes that does not cause pain. Lymph nodes are groups of cells found along the path of lymphatic vessels. They filter the lymphatic fluid and remove harmful substances. The most common sites of lymph node swellings are in the neck, armpit, groin, or the abdomen.
General symptoms can include fever, sweating, fatigue, loss of appetite, and bony pain.
There are no known strategies to prevent lymphoma.
What Are the Causes of Lymphoma?
In most cases, the cause of lymphoma remains unknown.
Patients with HIV (Human Immunodeficiency Virus) have a higher risk of developing lymphoma.
Stomach lymphoma can be caused by an infection in the stomach called Helicobacter Pylori. This infection is sometimes found in people that have stomach ulcers.

Sarcoidosis is an inflammatory disease that can affect almost any organ in the body. It causes heightened immunity, which means that a person’s immune system, which normally protects the body from infection and disease, overreacts, resulting in damage to the body’s own tissues. The classic feature of sarcoidosis is the formation of granulomas, microscopic clumps of inflammatory cells that group together (and look like granules, hence the name). When too many of these clumps form in an organ they can interfere with how that organ functions.
Sarcoidosis is a multi-system disorder. Symptoms typically depend on which organ the disease affects. Most often the disease will affect the lungs.
General: About one third of patients will experience non-specific symptoms of fever, fatigue, weight loss, night sweats and an overall feeling of malaise (or ill health).
Lungs: The lungs are affected in more than 90% of patients with sarcoidosis. A cough that does not go away, shortness of breath, particularly with exertion and chest pain occur most frequently with the pulmonary form of the disease.
Lymph Nodes: Up to 90% of sarcoidosis patients have enlarged lymph nodes. Most often they are in the neck, but those under the chin, in the armpits and in the groin can be affected. The spleen, which is part of the lymphatic system, can also be affected.
Liver: Although between 50% to 80% of patients with sarcoidosis will have granulomas in their liver, most are without symptoms and do not require treatment.
Heart: Researchers estimate that cardiac sarcoidosis, affects more than 10 percent of people with sarcoidosis in the United States, and perhaps as mHeart: any as 25 percent. Sarcoidosis can cause the heart to beat weakly resulting in shortness of breath and swelling in the legs. It can also cause palpitations (irregular heartbeat).
Brain & Nervous System: From 5% to 13% of patients have neurologic disease. Symptoms can include headaches, visual problems, weakness or numbness of an arm or leg and facial palsy.
Skin: One in four (25%) of patients will have skin involvement. Painful or red, raised bumps on the legs or arms (called erythema nodosum), discoloration of the nose, cheeks, lips and ears (called lupus pernio) or small brownish and painless skin patches are symptoms of the cutaneous form of the disease.
Bones, Joints & Muscles: Joint pain occurs in about one-third of patients. Other symptoms include a mass in the muscle, muscle weakness and arthritis in the joints of the ankles, knees, elbows, wrists, hands and feet.
Eyes: Any part of the eye can be affected by sarcoidosis and about 25% of patients have ocular involvement. Common symptoms include: burning, itching, tearing, pain, red eye, sensitivity to light (photophobia), dryness, seeing black spots (called floaters) and blurred vision. Chronic uveitis (inflammation of the membranes or uvea of the eye) can lead to glaucoma, cataracts and blindness.
Sinuses, Nasal Muscosa (lining) & Larynx: About 5% of patients will have involvement in the sinuses with symptoms that can include sinusitis, hoarseness or shortness of breath.
Other Organs: Rarely, the gastrointestinal tract, reproductive organs, salivary glands and the kidneys are affected.
