What are the symptoms of cancer?

Cancer Symptoms, and what Cancer may this be?

• My mom has always had these little sores on her arms, and she would always pick at them and she still gets sores on her arms and she still picks at them. Some of them have dry discolored skin on them, it's crusty too. Also if she laughs hard enough or even so much coughs she will urinate herself, she won't even feel it that she even had to. She has body aches all over, she says her skull feels like it is on fire and her feet and other parts of her body will go numb, and she feels pins and needles in her feet and hands. Doctors checked her for Fibromyalgia and they are checking her for MS. but she also has a very weak immune system and she is ALWAYS tired. She has random blood spotting weeks before she is supposed to have her period also, and she is very week and has to pull herself up stairs, and she even feels like she can fall over at any given time. She's been sick for 2 years with all of these symptoms and they just seem to get worse, but the sores on her have always been there. Her thyroid is always out of whack also.. I just want to know... do these seem like cancer symptoms? If so, what kind of cancer? I hope you can help!

• Answer:

  I'm sure the doctors would have discovered any cancer by now. If one doctor cannot supply the answers then see another one. Whatever she has I'm certain she is not the first person to have it and somebody can figure it out.
