The above mentioned are more specific symptoms for each different type of cancer but even if you have that cancer, it does not mean you would have that symptom, and vice versa even if you have that symptom, it does not mean you have that cancer.
Better check with your doctor.
PS. many ppl like to go for body checks but they do not know what to look for, that's why it's wiser to check for certain common diseases instead of blindly checking for unnecessary stuff while wastinr your own money!
