Immunotherapy: New hope in Cancer Treatment

Here are some tips about Immunotherapy: New hope in Cancer treatment

One of the most asked questions and researches in the medical world, Is there a treatment for cancer? However, there is good news and supposedly ‘immunotherapy’ has become a clinically validated treatment for many types of cancers.


What is Immunotherapy?

Immunotherapy is a type of cancer treatment in which medications are used to strengthen the immune system to help it fight cancer. The immune system is made of white blood cells (also called T cells), and organs and tissues of the lymph system that helps to fight pathogens and keep diseases and illnesses at bay.

Immunotherapy is a biological therapy that uses substances from living organisms to treat cancer.


Types of immunotherapy

There are several types of immunotherapy to fight cancer cells. They can either aid the immune system to fight cancer directly or stimulates the immune system in a general way.


Checkpoint Inhibitors – These drugs do not attack the tumours and prevent the T cells from directly killing the cancer cells. Instead, they inhibit the ability of the cancer cells to attack the immune system.

Adoptive cell transfer – For this treatment, doctors extract T cells from a tumour and those that are most active against cancer are grown in large batches in laboratories in 2-8 weeks time. Chemotherapies and radiation therapies are used till the T cells are injected back to your veins.

Monoclonal antibodies – These antibodies grown in laboratories are used as targeted therapy to block the abnormal protein in a cancer cell. Monoclonal antibodies are more considered to be a targeted therapy rather than immunotherapy.

Treatment Vaccines – These boost the immune system’s response to fight cancer cells.


Who can use immunotherapy?

Immunotherapy is not just as widely used as chemotherapy, radiation therapy or surgery. But they are approved to treat many different forms of cancer.
