Deciding when to have a baby is never simple. Pregnancy at any age has its own advantages and disadvantages.
Considering the fact that as you age, your breasts change along with the rest of your body. In your 20s, your breasts are firm and have good elasticity and tone. If you’re trying to get pregnant in your 20s, time is on your side – and biology is, too.
As you enter your 30s, hormones like estrogen help to keep breasts firm. This decade, which has become more popular for childbearing and breastfeeding, offer mothers some long-term protection against breast cancer. In your 40s, however, breast tissue starts to decline and the percentage of fat in your breasts increases, also there are increased risks associated with pregnancy.
Relationship Between Pregnancy And Breast Cancer Risk
- Studies have shown that a woman’s risk of developing breast cancer is related to her exposure to hormones that are produced by her ovaries . Pregnancy and breastfeeding have direct effects on breast cells, causing them to differentiate, or mature, so they can produce milk. Some researchers hypothesize that these differentiated cells are more resistant to becoming transformed into cancer cells than cells that have not undergone differentiation.
- Women who have their first full-term pregnancy at an early age have a decreased risk of developing breast cancer later in life.
- The older a woman is when she has her first full-term pregnancy, the higher her risk of breast cancer. Women who are older than 30 when they give birth to their first child have a higher risk of breast cancer than women who have never given birth.
- Women’s risk of breast cancer is modestly increased following her first full-term pregnancy, but it then falls gradually and is not affected by subsequent pregnancies.
- With every five-year increase in the age at which a woman has her first full-term pregnancy, her odds of developing breast cancer rise by 7%.
