Thank you for getting in touch with us. As I see, you aunt is suffering from breast cancer
which has spread to various parts of the body. If treatment is delayed for any kind of malginant cancer, it usually starts spreading to the lymph
nodes and other parts of the therapy. Therefore, treatment is started as soon as the diagnosis is made and sometimes even with a provisional diagnosis in hand. Sometimes, even the medicines which are used in chemotherapy
have many side effects and can lead to severe morbidity. One of them is fluid in the lungs. The fluid needs to be eliminated as soon as possible as it can lead to severe complications like infection, inflammation etc. Sometimes that fluid needs to be drained while in some cases, it can be taken care of by medicines. The prognosis for your aunt does not look that good at the moment and you should make sure that you guys provide her full support. Hope this helped.
