There is continued controversy over regardless of whether capsaicin acts as a carcinogen, co-carcinogen, or anti-carcinogen. For example, capsaicin has demonstrated chemopreventive and antiproliferative effects against various cell lines including breast, bladder, prostate cancer cells.

From statistical analysis, the authors found a robust association among stomach cancer and capsaicin pepper . Having said that, these authors also noted that other underlying unidentified ethnic, social, or cultural things, for which high pepper use is a marker in the 3 diverse cultures, could be accountable for the observed associations. Researchers from Sungkyunkwan University proposed that capsaicin altered the metabolism of chemical carcinogens and could possibly promote carcinogenesis at higher doses . On the other hand, in an Italian case–control study, chili was briefly described as being protective against stomach cancer . However, this getting was refuted by others , who indicated that chili peppers are not heavily consumed in northern Italy, exactly where the study was carried out.

The “heat-sensation” of capsaicin arises due to the binding of capsaicin to transient receptor possible vanilloid ion-channel receptors . Capsaicin functions as a higher affinity agonist of the TRPV1 receptor . Other capsaicinoids besides capsaicin also generate the “heat-sensation” via the TRPV1 receptor. Nonetheless, some of the biological activities of capsaicin, like its anti-neoplastic, cardioprotective effects, have been identified to be independent of the TRPV1 receptor. Much more research is essential to elucidate the molecular mechanism underlying these TRPV1-independent effects of capsaicinoids.
