I'm 18 years old and recently got an ultrasound found 4 nodules and 3 need to have a biopsy. does my age or number of nodules increase risk of cancer?

Await biopsy results: at your age,I assume you are referring to breast cysts or nodules. Wait for biopsy results and certainly continue to examine your own breasts arm armpit areas.

Depends: Where are the nodules found? If found on breast then there is a probability that it is cancer,If found on liver or anywhere else then probability is very low at your age.

More cancer in older: Pediatric thyroid cancer is extremely rare, affecting just one child in million under age 10 and rising to about 15 children per million in teens ages 15 to 19. In most cases,prognosis very good. Usually nodules biopsied when1.0-1.5 cm in size and are solid or mixed echogenicity on ultrasound.More than 95% of all thyroid nodules are benign (non-cancerous growths). Multiple nodules no increase ca.
