TLDR Men with frontal male pattern baldness may have a higher risk of gastric cancer.

In a prospective cohort study of 219,425 men from the UK Biobank, researchers found that frontal male pattern baldness was associated with an increased risk of gastric cancer, with an adjusted hazard ratio of 1.52. During the 8-year follow-up, 309 cases of oesophageal cancer and 210 cases of gastric cancer were identified. The study did not find significant associations between other hormonal and reproductive factors and the risk of oesophageal or gastric cancers. This suggests that male pattern baldness, which is often considered a proxy for sex hormone levels, may be linked to gastric cancer risk, and highlights the need for future studies to directly test circulating sex steroid hormone levels in relation to upper gastrointestinal cancer risk.

Antiandrogens and androgen inhibitors like spironolactone, finasteride, and dutasteride can treat hair loss and skin conditions, but they have risks and side effects, including potential harm to pregnant women and risks of cancer and heart issues. Herbal remedies also have antiandrogenic effects but lack safety validation.

research Androgenic Alopecia: Cross-Talk Between Cell Signal Transduction Pathways

1 citations, May 2017 in “InTech eBooks”

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.
