Hi

My mom 55 Years old gone through breast cancer surgery couple of months ago where her lymph node was also removed and she faced lyphodema and now recently a cut that has expand upto 4 inches in armpit not healing up. (she dont have diabetes ) 

She has completed her Chemotherapy and Radiation as well.

Fluid with bad smell appears daily basis and similar wound appeared on her same side of shoulder(backside) that is not healing please guide what it is and what measures should we take?

Oncologist suggested, just clean wound in armpit with pyodine and keep it clean.

Now a bubble kind of abscess also appear on her hand with lyphodema.

We are living in Pakistan and here nobody guiding us what to do next.

We are very much worried why its not healing up?

Any help would be appreciated

Thanks

Umar
