Doctors usually require us to get blood tests to see if there are abnormalities that mix up in our bloodstream. Depending on the amount of blood taken out from you, it is usually difficult to know if you have cancer cells. There are multiple types of cancer and one blood test would not give a good result.
Doctors usually require an MRI, ultrasound and a battery of tests if they suspect cancer cells are present in your body. For example, if any member of your family has breast cancer, there is a possibility that you may develop one. Proof of cancer being hereditary has not been proven yet, but it is better to know early than learn it on the late stages.
Have a general check up instead if you feel something is bothering you but you cannot pinpoint it.
That's hard to say ,if you feel it's very pain,and I suppose you go tee see the doctor and check carefully again on it.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
