Why does pregnancy cause breast cancer

Can you get breast cancer during pregnancy? Many people probably think that women who do not give birth or breastfeed have a higher chance of getting breast cancer. In fact, we cannot ignore the fact that women can also get breast cancer during pregnancy and breastfeeding. Maternal breast cancer, also known as gestational breast cancer, refers to breast cancer diagnosed during pregnancy or within 1 year after childbirth. So, what are the causes of breast cancer in pregnant women?

Because breast cancer is a tumor that responds to hormones, the increased levels of estrogen and progesterone in the blood circulation during pregnancy will accelerate tumor growth and metastasis. These estrogen and progesterone act on the breast, causing the capillaries to increase and become congested. In addition, many expectant mothers consume a large amount of high-hormone tonics during pregnancy, which accelerates tumor growth. In addition, some obstetricians do not pay enough attention to breast examinations, which can easily delay diagnosis.

Therefore, early diagnosis and timely treatment are key factors in improving the prognosis of breast cancer during pregnancy. Doctors remind that breast examinations should never be neglected during pregnancy. Patients with breast hyperplasia or lobular nodules before pregnancy should pay more attention to regular breast examinations during pregnancy. In addition, the diet during pregnancy should be diversified and scientific, and you should not blindly follow the trend of eating tonics.

Chemotherapy cannot be used in the first three months of pregnancy, and radiotherapy should not be performed during the entire pregnancy. This principle is the basis of the guidelines. During pregnancy, due to the stimulation of estrogen, the breasts generally proliferate and swell. At this time, many breast lumps and lactation are considered normal reactions, which can easily delay the disease. Therefore, a thorough breast examination must be performed during the first obstetric examination. Fortunately, breast examination using ultrasound during pregnancy is actually very safe for the majority of pregnant women.
