Most breast lumps women feel - 8 out of 10 - aren't cancer. It's more common for them to be a cyst (a sac) or a fibroadenoma (an abnormal growth that's not cancer). Some lumps come and go during a woman's menstrual cycle. When you feel a lump in your breast, it's understandable to be concerned. B....
Yes. It is important to get any lump in your breast checked by a doctor, even if it is not painful. Not all lumps are cancerous, but some could be cysts or benign growth but only a medical professional can determine what it is.
In general, yes it is safe. But there are exceptions based on the conditions. A woman who is developing breast cancer might be excreting small amounts of fluids from the nipples. A woman who is lactating (to feed babies) is also ‘leaking’ fluids. Now, whenever a fluid is exchanged between two bod....

Yes, PARP inhibitors are relatively newer class of drugs and scientists have just begun to explore their functionality and usage in Cancer treatment. LYNPARZA is the first and only PARP inhibitor approved in 2 distinct settings: For the maintenance treatment of adult patients with recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer, who are in complete or partial response to platinum-based chemotherapy. For the treatment of adult patients with suspected deleterious germline BRCA-mutated advanced ovarian cancer which has been treated with 3 or more prior lines of chemotherapy. Patients should be selected for therapy based on an FDA-approved companion diagnostic for LYNPARZA. Poly (ADP-ribose) Polymerase, or PARP, enzymes mediate DNA repair by transferring ADP-ribose units to preexisting ADP-ribose chains on proteins and to proteins. This ADP–ribosylation process recruits DNA repair enzymes, thereby maintaining genomic integrity. Inhibiting this process can lead to the accumulation of DNA damage and, ultimately, cell death.
