Test will convert to DHT but it will also convert to estrogen and can contribute to estro related cancers. DHT would not help some guy with high psa numbers and a genetic likelihood for prostate cancer. so masteron is not an anti cancer med by any means. Just specific estro related cancers in the womensis breastasis.
Go on PubMed and do a search. There are studies published, but I don't think you will get someone else to do your homework for you... And yes, a lack of test can cause problems. Not sure if there will be links to cancer though.
