“Lymphoma” Cancer is one of the worst illnesses that face humanity. There are many types of cancers that affect our health and may lead us to death. Lymphoma is one of the most common cancers and we are going to see its causes, symptoms and testaments. Lymphoma is a type of cancer that begins in immune system cells called lymphocytes. Like other cancers, lymphoma occurs when lymphocytes are in a state of uncontrolled cell growth and multiplication. Lymphoma can be the result of a genetic predisposition that is inherited from family members. It is possible to be born with certain genetic mutations or a fault in a gene that makes one statistically more likely to develop cancer later in life. Also, Carcinogens are a class of substances that are directly responsible for damaging DNA, promoting or aiding cancer. Exposure to certain pesticides, herbicides, and solvents such as benzene has been associated with lymphoma. Similarly, black hair dye has been linked to higher rates of NHL. When our bodies are exposed to carcinogens, free radicals are formed that try to steal electrons from other molecules in the body. These free radicals damage cells, affecting their ability to function normally, and the result can be cancerous growths. As we age, there is an increase in the number of possible cancer-causing mutations in our DNA. The risk of NHL increases as we age, and HL is most common between ages 16-34 and 55 years and older. Additional medical conditions that have been associated with higher lymphoma rates include infection with HIV, human T-lymphocytic virus type 1 (HTLV-1), Epstein-Barr virus, Helicobacter pylori, or hepatitis B or C; autoimmune disease (such as lupus); diseases that require therapies that suppress the immune system; and any other immunodeficiency diseases. Cancer symptoms are quite varied and depend on where the cancer is located, where it has spread, and how big the tumor is. Lymphoma usually is first present with swelling in the neck, underarm, or groin. Additional swelling may occur where other lymph nodes are located such as in the spleen. In general, enlarged lymph nodes can encroach on the space of blood vessels, nerves, or the stomach, leading to swollen arms and legs, to tingling and numbness, or to feelings of being full, respectively.
Lymphoma symptoms also include nonspecific symptoms such as fever, chills, unexplained weight loss, night sweats, lethargy, and itching. In addition, there are several treatments to combat this disease. For instance, Chemotherapy that utilizes chemicals that interfere with the cell division process - damaging proteins or DNA - so that cancer cells will commit suicide. These treatments target any rapidly dividing cells (not necessarily just cancer cells), but normal cells usually can recover from any chemical-induced damage while cancer cells cannot. Chemotherapy is generally used to treat cancer that has spread or metastasized because the medicines travel throughout the entire body. Treatment occurs in…
