Research published in the scientific journal Nature pointed out the causes for cancer cells to “wake up” in the lung after breast cancer treatment.
The study, conducted by the Cancer Research Institute, in the United Kingdom, revealed that it is possible to block a lung protein, where the tumor is installed, with a drug used to treat chronic myeloid leukemia.
A CNN Radio gynecologist Rosemar Rahal, who is a member of the Brazilian Society of Mastology, said that the study refers to the most frequent tumor in the breast.
“Even if it is discovered at the beginning, it evolves with recurrence and metastasis, sometimes 20 years later and the researchers sought to understand the reason for this recurrence of the disease.”
According to the specialist, “some cell probably becomes dormant, like in the lung, and something happens there that makes the tumor grow again.”
“Then they studied the blocking of the growth of these cells”, he added.
The scientists, according to the gynecologist, “realized that when using the drug, it blocks the microenvironment of tumor growth, preventing the proliferation of tumor cells.”
The study is in the pre-clinical phase, that is, testing on animals and, therefore, there will be a delay for the drug, if it has proven efficacy in humans, to be marketed.
Rahal recalled that breast cancer is the second leading incidence of the disease in women, behind only skin cancer.
