19 warning signs that cancer is developing in your body

Frequent stomach cramps or stomach aches may be indicative of colorectal cancer.

14. A red, painful, or swollen breast

These symptoms may indicate inflammatory breast cancer. Call your doctor if you have any unexplained changes in your breasts.

15. Nipple changes

One of the most common changes that women remember noticing before being diagnosed with breast cancer is that the nipple becomes flattened, inverted, or turned to one side.
16. Abnormally heavy or painful periods or bleeding between periods

Many women report this as a sign of endometrial or uterine cancer. Request a transvaginal ultrasound if you suspect anything other than a normal heavy menstrual cycle.

17. Swelling of facial features
