What is cancer? in the most basic terms, cancer refers to cells that grow out-of-control and invade other tissues. Cells become cancerous due to the accumulation of defects, or mutations, in their dna. Certain inherited genetic defects (for example, brca1 and brca2 mutations) and infections can increase the risk of cancer. Environmental factors (for example, air pollution) and poor lifestyle choices -- such as smoking and heavy alcohol use -- can also damage dna and lead to cancer. Most of the time, cells are able to detect and repair dna damage. If a cell is severely damaged and cannot repair itself it undergoes so-called programmed cell death or apoptosis. Cancer occurs when damaged cells grow, divide, and spread abnormally instead of self-destructing as they should. Cancer symptoms and signs there are more than 100 different types of cancer. Every cancer and every individual is unique. The symptoms and signs of cancer depend on the size and location of the cancer as well as the presence or absence of metastasis. Symptoms and signs such as fever, pain, fatigue, skin changes (redness, sores that won't heal, jaundice, darkening), and unintended weight loss or weight gain are not unique to cancer, but they often occur with cancer. More potential cancer signs and symptoms include the presence of a lump, difficulty swallowing, changes or difficulties with bowel or bladder function, persistent cough, hoarseness, and unexplained bleeding or discharge.
