Why do we so often obsess about health problem rather than just doing something about it? If she has all these symptoms, she should see the doctor, even if she doesn't have cancer. Encourage her to go; offer to drive her if that's what is needed, if only for your own peace of mind. Also, yes, it is possible to have all these symptoms without having cancer. It's actually more likely not cancer even given all the symptoms. But regardless, its' worth getting her checked out because she is still sick either way. And stop Googling symptoms! Toe pain is so incredibly common it's not worth getting anxious about.
