Abstract

Obesity increases cancer risk, yet obese patients often respond better to cancer immunotherapy. In our study, we uncovered why: high estrogen levels, especially in obese men, boost the immune response triggered by immunotherapy. This reveals a key role for estrogens in improving treatment effectiveness.
