Do you have any thoughts on birth control pill consumption, estrogen increase from the pill, and breast cancer? It seems problematic that so many women are consuming synthetic estrogen for years, and I am curious if this can be related to breast cancer. It's really perplexing because I have been in rooms with doctors that tell patients the pill can actually lower their risk for cancers.

It is not the primary cause of breast cancer, environmental pollutants, xenoestrogens, pro-inflammatory diet, excess alcohol consumption, lack of antiinflammatory/antioxidnat foods in the diet etc are (as well as some genetic links).

Breast cancer: An analysis of data from more than 150,000 women who participated in 54 epidemiologic studies showed that, overall, women who had ever used oral contraceptives had a slight (7%) increase in the relative risk of breast cancer compared with women who had never used oral contraceptives. Women who were currently using oral contraceptives had a 24% increase in risk that did not increase with the duration of use. Risk declined after use of oral contraceptives stopped, and no risk increase was evident by 10 years after use had stopped (4). A 2010 analysis of data from the Nurses’ Health Study, which has been following more than 116,000 female nurses who were 24 to 43 years old when they enrolled in the study in 1989, also found that participants who used oral contraceptives had a slight increase in breast cancer risk (5, 6). However, nearly all of the increased risk was seen among women who took a specific type of oral contraceptive, a “triphasic” pill, in which the dose of hormones is changed in three stages over the course of a woman’s monthly cycle. An elevated risk associated with specific triphasic formulations was also reported in a nested case–control study that used electronic medical records to verify oral contraceptive use (7). In 2017, a large prospective Danish study reported breast cancer risks associated with more recent formulations of oral contraceptives (8). Overall, women who were using or had recently stopped using oral combined hormone contraceptives had a modest (about 20%) increase in the relative risk of breast cancer compared with women who had never used oral contraceptives. The risk increase varied from 0% to 60%, depending on the specific type of oral combined hormone contraceptive. The risk of breast cancer also increased the longer oral contraceptives were used.
