(CNN) -- A new treatment has been approved by the FDA in the fight against her2-positive breast cancer, giving some of the most vulnerable patients a chance to fight the disease from home.
The FDA has given a green light to Phesgo, a drug to treat adult patients with her2-positive breast cancer that is either in its early stages or has spread to other parts of the body.
Roughly one-fifth of breast cancers are her2-positive.
The FDA says Phesgo works by disrupting the signals which promote the growth of cancer cells.
It was initially used in combination with chemotherapy. Now, it can be administered at home through an injection under the skin by a qualified health care professional once chemotherapy is finished.
This gives those vulnerable to the coronavirus a way to fight cancer without being put at further risk of catching COVID-19.
