I've got the BRCA 1 (Breast Cancer) gene, so it's likely to be cancer. I've a higher risk of breast cancer, but in blokes with this gene the big threat is prostate cancer. I'm glad I know this, because I know to check myself more regularly than I would have done, and I should be having more blood tests before the rest of the population are eligible.
So, likely to be cancer.
If that is the case, and the diagnosis is grim, I will kill myself (Pills or morphine), or persuade someone to do it for me. Having seen my dad in his last few hours, that is no humane way to go.
However, if I get run over by a bus (Not sure why buses have such a bad reputation for killing people, as a lot of people die under trains) tomorrow then so be it. I've had a very interesting life so far, so I haven't wasted it.
