What birth effects accompany tumor?

* Premature birth. Tumors can put pressure on the uterus, causing it to contract and dilate prematurely. This can lead to the baby being born before it is fully developed, which can result in a number of health problems.

* Low birth weight. Tumors can also inhibit the growth of the baby, leading to low birth weight. This can increase the risk of premature birth and other health problems.

* Birth defects. Tumors can also cause birth defects, such as cleft lip and palate, spina bifida, and heart defects.
