Cancer Prevention
Cancer is the result of the uncontrolled growth of abnormal cells anywhere in the body.
A. TRUE
B. FALSE
A. True
Explanation:
Cancer results from the uncontrolled growth of abnormal cells anywhere in the body (blood, brain, bone, or any organ) and many of these abnormal cells are capable of invading other tissues.
Cancers are often named for the organ or cell type where the abnormal cells first develop. Terms such as liver cancer, lung cancer, brain cancer, and many others refer to where the abnormal cells started to develop. When these cancer cells leave their original developmental site they are termed metastatic cancer.

What kind of foods are linked to colon cancer?
A. Processed meats
B. Microwavable foods
C. Foods with salt substitutes
D. Shellfish
A. Processed meats
Explanation:
Meat processing involves the addition of preservatives like sodium nitrite or products that enhance color and flavor. The meat is also sometimes smoked, which may also create compounds that might increase cancer risk. Studies have shown that consuming large amounts of processed meat is associated with an increased risk of developing colorectal cancer. One potential explanation for this association is that nitrites are added to many lunch meats, hot dogs, ham products, and other processed meats.

______________ is the most deadly of all cancers of the female reproductive system.
A. Uterine cancer
B. Vaginal cancer
C. Cervical cancer
D. Ovarian cancer
D. Ovarian cancer
Explanation:
Ovarian cancer is the most deadly of all cancers for women because most ovarian cancers are not detected early and the cancer cells have spread beyond the ovaries to the pelvis and lymph nodes when they are first detected. Unfortunately, symptoms of ovarian cancers often only appear in the late stages of ovarian cancers (late-stage cancers are difficult to treat).
