Still was fighting late last year too (and winning!) That's crazy
Quite crazy yeah.
I guess that fighters have many opportunities to get checked for internal damage/anomalies, but then some cancers can be lightning fast, with only weeks between the diagnosis and death (pancreatic cancer is one of those bitches) while others involve grueling battles for years with atrocious pain (the primitive cancer can be hard enough to endure, but things like bone metastases reportedly cause some of the worst pain you can experience.
And added to the symptoms of the cancer/metastasis. You also have to deal with chemo, pain killers (often the strongest ones like fentanyl) and a loadshit of side effects (who might require themselves some additionnal medication), and often, frequent surgeries.
And, maybe the worst of all, is your psychological state, battling with all that shit, knowing well that in some cases, remission, healing and survival would be a miracle.
I say it again, do everything to avoid that ; if a cancer gets diagnosed soon enough, it's possible to beat the shit outta him, and to heal fully.
Any unusual symptoms : go check it please.
