NEW YORK (Reuters Health) – Chemotherapy for breast cancer could contribute to the transmission of the disease to the lungs, researchers at the Swiss Institute for Experimental Cancer Research, led by Professor Michel de Palma, said .
According to the website of the British newspaper "Daily Mail", reportedly caused chemotherapy drugs paclitaxel Anddoxorubicin Commonly described as breast tumors by releasing proteins into the blood until they reach the lungs, leading to the emergence of the disease in a new part of the body.
When scientists blocked the protein in a laboratory model, the cancer did not spread and they hope their results will help make chemotherapy more effective.
Before surgery, chemotherapy is often given to patients with breast cancer to reduce the number of tumors and facilitate their elimination. This procedure is known as "regenerative therapy" and also helps preserve healthy breast tissue.
In some cases, chemotherapy may even completely eliminate the tumor, but the treatment does not always reduce the tumors: if the growth resists, the new treatment is more likely to spread to other parts of the body.
The number of cases of the disease is unclear, but researchers found that the lungs, bones, liver and brain were the most affected secondary areas.
The researchers also confirmed that their results should not discourage people from receiving chemotherapy when needed.
