WebUncontrolled Cell Divisions Create Tumors including Cancers. Tumors, including cancers, are caused by abnormal cells that multiply continuously. If the abnormal cells continue to divide unstopped, they can damage the tissues around them, spread to other parts of the body ( malignancy ), and even result in death. WebYes, cancer is a genetic disease. It is caused by changes in genes that control the way cells grow and multiply. Cells are the building blocks of your body. Each cell has a copy of your genes, which act like an instruction …

WebCommon cancer-related causes of low blood cell counts include: Chemotherapy. Certain chemotherapy drugs can damage your bone marrow — the spongy material found in your bones. Your bone marrow makes blood cells, which grow rapidly, making them very sensitive to the effects of chemotherapy. WebThese cells that are uncontrollably dividing are also not doing their normal jobs. They are diverting bodily resources and not performing vital functions. For example, if you have tumor in your heart those cancer cells in that tumor are not doing what normal heart cells do, work together to pump blood. The actual immediate cause of death varies. WebDec 23, 2024 · Chemo works by halting cancer cell division, often by interfering with RNA or DNA synthesis, and shrinking the tumor.

"WebCancer cells tend to divide quickly and grow out of control. Radiation therapy kills cancer cells that are dividing, but it also affects dividing cells of normal tissues. The damage to normal cells causes unwanted side effects. Radiation therapy is always a balance between destroying the cancer cells and minimizing damage to the normal cells.
