CANCER GROWTH AND METASTASIS
Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. A healthy body have trillions of cells it’s made of grow and divide because the body needs them to function daily. Healthy Cells have a specific life cycle, reproducing and dying off in a way that is determined by the type of cell. New cells take the place of the old or damaged cells as they die. Cancer disrupts the process and leads to abnormal growth in cells. It’s caused by changes or mutations in DNA. DNA exists in the individual genes of every cell. It tells the cell what functions to perform and how to grow and divide. Mutations occur frequently in DNA, but usually cells correct these mistakes. When the mistake is not corrected a cell can become cancerous.
The general types of cancer- Carcinoma -a cancer that starts in the skin or the tissues that line other organs. Sarcoma – a cancer of connective tissues such as bones, muscles, cartilage and blood vessels. Leukemia – a cancer of the bone marrow which creates blood cells. Lymphoma and myeloma are cancers of the immune system. Risk Factors of Cancer can be exposure to cancer-causing chemicals called carcinogens; exposure to radiation; unprotected exposure to the sun; viruses such as human papilloma virus; smoking; lifestyle choices such as your diet and level of physical activity.
TIPS & ADVICE
There are several ways to prevent cancer. Stop using tobacco and avoid second hand smoke; eat a healthy balanced diet such as limit the intake of processed meats, avoid alcohol or drink in moderation, keep a healthy weight and stay active by getting 30 minutes of physical activity every day, get vaccinated against viral infections that can lead to cancer such as Hepatitis B and HPV, practice safe sext and don’t share needles when using drugs or prescription medication, see your doctor regularly and have screening done for various types of cancer. The most common treatment for cancer are – Surgery which removes as much of the cancer as possible; Chemotherapy- medications that are toxic to cells to kill rapidly dividing cancer cells; Radiation Therapy-a powerful focused beams of radiation inside or outside your body to kill cancer cells; Stem Cell (bone marrow) Transplant- Repairs diseased bone marrow with health stem cells. These cells are undifferentiated cells that can have a variety of functions. Transplant allows doctors to use higher doses of chemotherapy to treat the cancer.
