Health Education for Cancer Patients and Their Families

Cancer can be divided into two main categories: blood cancers, including leukemia and lymphoma (cancers of the lymphatic glands), and solid cancers, which affect the tissues of other parts of the body. These solid cancers are further divided into carcinoma and sarcoma.

• Lymphoma: Cancer cells in lymphoma originate in the lymph nodes, causing large masses of tumors in areas where the lymph nodes are found, such as the chest, armpits, abdomen, and groin.
• Leukemia: Leukemia begins in cells responsible for blood production in the bone marrow, affecting its ability to produce normal blood cells.

Carcinoma: This type of cancer is more common in older adults compared to the young, originating in cells lining internal organs, the lungs, digestive system, and skin. Examples include thyroid, prostate, colon, breast, skin, and lung cancer.

Sarcoma: Unlike carcinoma, sarcomas are more common in younger people than in the elderly. This type of cancer originates from mesodermal cells, which form connective tissue, muscles, bones, and blood vessels. Examples include osteosarcoma (bone cancer) and smooth muscle sarcoma, which develops in the smooth muscles of the stomach.
