I used to keep the laptop on my thighs for about 6 hours a day for about 3 or 4 years and now i am experiencing pain in my thighs and in my knees. Is there any chance i can get bone cancer from the laptop being on my lap for that long? I think theres radiation in laptops? Im so worried. For the past year i have tried not to rest the laptop anywhere on my body but now i feel like the 4 years that i did has given me bone cancer. Can this happen?
