“Will the dream of making a cancer vaccine come true soon?”

According to an estimate, by the year 2025, the number of people suffering from some form of cancer across the world may reach 20 million.

But as medicine has succeeded in preventing many diseases through vaccines, there is hope that cancer can also be treated through them.

In April 2024, the melanoma cancer vaccine was given to patients for the first time in Britain as a trial.

A vaccine developed to fight lung cancer is being used as an experiment or trial in seven countries.

At the same time, scientists at the University of Florida have created a vaccine that can prevent the most common type of brain cancer.

In fact, these new methods of treatment have started with the vaccine made during the Kovid epidemic. Especially the vaccine which is based on mRNA technology.

Vaccines made with this technology are more effective than vaccines made with traditional technology. Now trials of many types of cancer vaccines are going on, so this week in Dunya Jahan we will try to know whether the cancer vaccine can come soon?

What is Cancer?

Our body is made up of billions of cells. In cancer, some cells start forming and growing in an uncontrolled manner. The form of cells of different types of cancer is different.

There are about 200 types of cells in our body which form various parts of our body. These cells work on the basis of the signals they receive which are called DNA.

Whenever new cells are formed, a copy of their DNA is also made but sometimes the copy of DNA is not made correctly.

These damaged cells start working on the basis of wrong signals due to which their number increases in an uncontrolled manner and tumors or lumps are formed inside the body.

“Every breakthrough begins with a dream, and the journey to a cancer vaccine is a testament to humanity’s unwavering hope and determination.”

What is the difference between a normal tumor and a cancerous tumor?

Many types of tumors can develop in our body. Normal tumors do not harm the body, but tumors whose cells do not work according to DNA signals are called cancerous. “It can be seen through a microscope that the shape of these cells has changed a lot from their original form.”

If the cells stop working according to the rules, then it affects many parts of the body and they are not able to work properly. But why does this happen?

There can be many reasons for this. Age, eating habits, environmental effects, viruses, smoking, genetic effects and our genes can also be the cause of cancer.

How can cancer be cured?

Treatment through surgery is possible due to early detection of many types of cancer. Along with this, cancer is also treated by medicine, chemo therapy, radiation and immune therapy. “

But chemo therapy or radiation attempts to prevent cancerous cell, but it also has many side effects or side effects. This also damages healthy tissue or tissues of the body.

But can the immunity or immunity of our body play a role in it?

Cancer cells offer such protein to their surface to hide from the body’s immunity or immune system that the body’s resistance system is not able to identify and destroy them.

But through immunotherapy, this mechanism can identify the cancerous cell and can also destroy them from where they cannot be destroyed through surgery or chemo therapy.

New hope

Patrick Ott, clinical director at the Melanoma Disease Center at the Dana-Farber Institute, believes the vaccine can provide long-term immunity to fight cancer.

Are vaccines a better option because they do not pose the risk of side effects that arise from treatment through chemotherapy or radiation?

According to Patrick Ott, “This is absolutely correct. The function of the vaccine is that it prepares the immune system to target only the androgen that is present only in the cancer tumor. In the same way that the vaccine Targets only the specific virus, whereas other methods of cancer treatment also damage healthy tissues.”

But for example, if a patient has blood cancer, then how and when will the vaccine be used in his treatment?

Patrick Ott says that it is difficult to tell right now, “Many scientists believe that the most effective use of the vaccine will be when doctors remove cancerous cells from the body through surgery. However, even after surgery, some cancer cells remain in the body. The vaccine can prevent those remaining cancer cells from growing again and returning.

But it does not seem that vaccine alone will be enough to treat cancer. There is a reason for this. Patrick Ott says that the vaccine takes time to prepare the body’s immune system to fight cancer.

Therefore, this method of treatment would not be suitable for a patient whose cancer is spreading in his body. Because he needs such treatment which can immediately stop the cancer from spreading.

Patrick Ott also says that cancer cells that are hidden in the body but have not become active can be eliminated through the vaccine.

Additionally, the vaccine trains the body’s immune system to identify and destroy cancer cells, which persists for decades.

This means that the body can be protected from getting cancer again for decades.
