Hi.. My Mum had breast cancer just over 5 years ago. She got a cold about 3 weeks ago that lasted 5 days, during that time she noticed her glands and the left side near her ear were swollen, this still hasn t gone down, it doesn t hurt, the doctor has taken her blood and she has slightly raised calcium , do you think this could be related to breast cancer? Or do you think it could be linked to her cold?
