Benign tumors are noncancerous and do not spread to nearby tissues.īut sometimes, tumors can grow large and cause problems when they press against neighboring organs and tissue. Tumors can cause health problems, depending on where they grow in the body. These extra cells can divide uncontrollably, causing tumors to form. Mutations can cause cells that should be replaced to survive instead of die, and new cells to form when they’re not needed. When a mistake is not corrected, a cell can become cancerous. Mutations occur frequently in DNA, but usually cells correct these mistakes. The DNA in each cell has instructions that tell the cell what to do and how to grow and divide. It’s caused by changes or mutations in the cell’s DNA. As cells become damaged or die off, new cells take their place.Ĭancer disrupts this process and causes cells to grow abnormally. Each one has a life cycle determined by the type of cell. Normal cells in your body grow and divide. How does cancer grow and spread? Abnormal cell division If you are experiencing unexplainable symptoms, it is best to contact a doctor for a diagnosis. Specific types of cancers often have their own warning signs. Signs and symptoms of cancer can include: While recognizing cancer warning signs may help people with cancer seek diagnosis and treatment, some cancers may be harder to detect early and may not show symptoms until the later stages. If you have a family history of cancer or have a high risk of developing cancer, it is important to follow a doctor’s screening recommendations. In people at a high risk, screenings may be recommended earlier. Mammograms to test for breast cancer are recommended for women ages 45 and older, but you may choose to begin screenings at age 40. At-home testing kits may also be able to detect some forms of colorectal cancer, according to a 2017 review of research. These screenings are typically performed during a colonoscopy. The American Cancer Society (ACS) recommends regular screenings for colorectal cancer beginning at age 45. Skin cancer screenings may be performed by a dermatologist if you have skin concerns or are at risk of skin cancer. Screenings for lung cancer may be performed regularly for those who have certain risk factors. Some screenings, such as for cervical cancer and prostate cancer, may be done as part of routine exams. Some common cancer screenings may detect: This can increase the effectiveness of treatment and lower the mortality rate.Ĭancer screenings may help detect signs of cancer early.

Lymphoma and myeloma are cancers of the immune system.Leukemia is a cancer of the bone marrow, which creates blood cells.Sarcoma is a cancer of connective tissues such as bones, muscles, cartilage, and blood vessels.Carcinoma is a cancer that starts in the skin or the tissues that line other organs.There are also several clinical terms used for certain general types of cancer: For example, a cancer that begins in the lungs and spreads to the liver is still called lung cancer. An example is ulcerative colitis, a chronic inflammatory bowel disease.Ĭancers are named for the area in which they begin and the type of cell they are made of, even if they spread to other parts of the body.
