What is the term for abnormal male breast enlargement and male breast cancer?

Gynecomastia is the correct term for abnormal male breast enlargement, which can occur due to various factors such as hormonal imbalances, medications, or underlying health conditions. This condition is characterized by the proliferation of glandular breast tissue. While not all instances of gynecomastia are indicative of breast cancer, it is important to note that gynecomastia can sometimes be associated with an increased risk of male breast cancer.

The other terms listed do not accurately describe abnormal male breast enlargement or male breast cancer. Andromastia is not a widely accepted term in the medical literature, and it does not specifically refer to the conditions mentioned. Masculinization typically refers to the development of male physical characteristics and does not pertain to breast enlargement. Pseudogynecomastia refers to the appearance of enlarged male breasts due to excess fat deposition rather than glandular tissue proliferation, which reinforces why gynecomastia is the appropriate term for describing the abnormal enlargement where actual breast tissue is involved.
