What makes Cancer, Cancerous?

The science behind cancer in layman terms

Did you know that 1 in 9 people in India are likely to have cancer once in their lifetimes? The cancer epidemic seems to be inching closer to everyone’s lives. Lung cancer and breast cancer are the most common amongst men and women respectively. A lot may even be known about cancer treatment and cancer surgeries. But you do not need to be a cancer specialist to know how cancer really works. We try to break it down for you in layman terms, the science of cancer.

What is a Cancer cell? 

The body is made up of a gazillion cells. All cells contain DNA that governs how the cells behave - when to grow, what work to do, when to multiply and when to die. When there is damage or change to the DNA then a mutation takes place and the cell no longer behaves like it should. These mutated cells tend to grow and multiply out of control. These cancer cells do not die like they should, nor do they mature. This can happen to any cell in any part of the body.

Growing Cancer

Cancer cells, unlike normal cells, multiply out of control and do not die. They also are able to hide from the immune system. They remain to be immature cells and thus do not have any specific job. They do not stick together and easily spread through the body through the blood and lymph nodes.

So as cells multiply, a tumor will grow. As the tumor grows, the cancer cells require more blood for oxygen and nutrients. So the cancer cells signal the tumor to make new blood vessels. This is called angiogenesis and it is how tumors grow big.

Cancer cells also create an enzyme that breaks down healthy cells and tissue. This allows it to grow into healthy tissue and is referred to as invasive cancer. When cancer cells break away from a tumor and spread to other parts of the body it is called metastasis. These are some terminology that one may encounter when their cancer specialist is staging the cancer.

Cancer treatment goals

The goal of any cancer treatment is to kill or remove as many cancer cells with the least damage to healthy normal cells. An oncologist is a doctor that has specialised in the diagnosing, staging and treatment of cancer. As a cancer specialist, the oncologist would draw out the best treatment plan that may involve cancer surgeries along with chemotherapy, immunotherapy, targeted therapy, etc.

Sometimes, even after a treatment, cancer can recur because all it takes is one cancer cell to be left behind. This is why your oncologist will pair more than one treatment to make sure no cancer cell is left behind. Many times one can be ‘cured’ of cancer but an oncologist will refer to it as a remission. This is when no symptoms of cancer can be seen. However, cancer can come back even after years.
