Answer:
C. interferon
Step-by-step explanation:
The hormone that may prove effective against brain and lung cancer is interferon. Interferons are a group of signaling proteins made and released by the body in response to viral infections or other pathogens. They are involved in regulating the immune system and have been found to have antiviral, antibacterial, and antitumor properties.
Interferons have been studied for their potential as cancer treatments, particularly for brain and lung cancers. They have been found to have antiproliferative and proapoptotic effects on cancer cells, meaning they can inhibit the growth of cancer cells and induce programmed cell death. Interferons can also stimulate the immune system to attack cancer cells.
Several types of interferons have been approved for use in the treatment of certain cancers, including melanoma, leukemia, and lymphoma. However, their effectiveness against brain and lung cancers is still being studied, and they may be used in combination with other treatments such as chemotherapy and radiation therapy.
In summary, interferon is the hormone that may prove effective against brain and lung cancer, due to its antiproliferative and proapoptotic effects on cancer cells, as well as its ability to stimulate the immune system to attack cancer cells.
