20 WARNING SIGNS THAT CANCER IS GROWING IN YOUR BODY

Abnormal periods or pelvic pain
Most women experience irregular periods and cramps from time to time. However, persistent pain and changes in your cycle may be a sign of cervical, uterine or ovarian cancer.
Change in bathroom habits
Significant changes in physical activity may indicate colon, prostate, or bladder cancer, among other cancers. Warning signs include persistent constipation and diarrhea; black or red blood in the stool; black, tarry stools; urinate more often; and blood in your urine.
