My 40 year old daughter has been diagnosed with cancer and has now developed a lump on the scalp behind her ear--it is midway from the top of her ear to the middle of it. She is experiencing headaches and has trouble holding onto things--she drops things. She also has an elongated tumor on her chest in the area where lymph nodes are. How serious are these tumors?
Hi, welcome to Chat Doctor firstly, you did not tell us what type of cancer your daughter have? What is the primary site of this cancer?  The features you described indicates presence of some lymph nodes. It should be confirmed by doing excisional biopsy.  It may be due to metastasis from the primary site.  Now, to talk with prognosis of a cancer patient, we need more information. If we suppose these lymph nodes to be due to metastasis then it can be said that the prognosis is not good.  Regards.
