Mai travelling kar rata early morning and empty stomach fir vomit hua or pura pani nikal gya or cough wagera sab nikal gya or fir ek cough aya jisme todha blood tha not dark red uske baad 15 min baad fir vomit hua lekin isme blood nahi aya or third time fir hua usme bhi blood nahi aya. Or vomit teeno baar forcefull hui thi kya reason ho sakta h first vomit m blood aane ka? Second question kya 27-28 ki age m lung cancer ya stomach cancer possible h?
