(0.8) how do i cure cancer?

So i went to get the radiocative capsule to make kerfur omega but only just then found out radiation can make me cancerous!!!!!!! I hoped i won't get cancer but I started coughing. I heard about the cancer meds but i cant find them in the shop, the meds that cost 500 points and are labeled as cancer meds. I couldn't write russian in the computer so i switched to english, and "cancer" keyword gave me nothing. What the hell am I supposed to do now?
