Many: There are many causes of lesions on the penis, many are benign or caused by sexually transmitted disease. These include papilloma (sometimes referred to as pearly penile papules), condyloma (genital warts caused by hpv), or genital herpes (caused by hsv).

Proof of cell: Phone link not yet in, microwaves are relatively safe, but radiation is in the electromagnetic spectrum and is a clear cause, and u-v light is part of the spectrum causing skin cancers. All seem to demonstrate direct links to dose and time of exposure. X-rays seem to have no threshold, but very low doses are very unliklely to lead to individual harm, but to a population, a small number will.

How come there are so many new drugs but we cannot find the cure for cancer?

Cancer is not: One disease, or one genetic chnge, but many. Drugs are poisons with side effects, and tumors are smart enought to learn to resist. Single genetic mutations are cured with miracle drugs. Many drugs now hope to keep cancers at bay and allow you to live with the cancer rather than obliterating it. The most fearsome of cancers is glioblastoma (brain tumors) and pancreas cancer. Few baby steps only.
