Questions and Concerns Relating to Cancer
The word cancer isn’t a pleasant thing to hear. It stirs a mix
of panic, worry and anxiety in all of us. In
India alone, the incidence of cancer is around 70-90 per
1,00,000 people. Its prevalence is established
to be around 2.5 million with more than 8,00,000 new cases and
5,50,000 deaths occurring each year.
On February 4, the world observes Cancer Day, to fight against
this global epidemic. As an initiative to
spread awareness, the medical experts at Narayana Health came
together to address the important
questions and concerns relating to cancer.
Dr. Sharat Damodar, Consultant Hematologist, who runs one of the
largest bone marrow center in the
country, along with Dr. Santosh Gowda, Medical Oncologist, and
Dr. Moni Kuriakose, Doctor and
Director of Head and Neck Surgery at Narayana Health, joined Dr.
Devi Shetty for a discussion. Through
an online Webinar session, called NH dialogues, the doctors
discussed topics such as the definition of
cancer, causes, symptoms, types, stages, prevention, treatment
methods, relapse risks, medical
advancements, mortality rates as well as lifestyle changes
necessary to keep cancer at bay.
About Cancer
The body is made up of cells. Each cell is programmed to
function in a certain way. In the case of a
cancer cell, this isn’t the case. A cancer cell undergoes
changes at the genetic level, i.e. the DNA
structure, which forms the blueprint of the cell. The cancer
cells are immature and dysfunctional cells
that innumerably divide and multiply, thereby, attacking the
body’s healthy cells, tissues and organs
and finally the immune system, resulting in the death of the
person. This is why cancer is termed as a
malignant disease; malignant means an evil disease that torments
and haunts a patient once hooked
on to. However, the good news is that if cancer is detected at
an early stage, it can be cured.
How does cancer creep into the system?
There is a high misconception that cancer is a hereditary
disease. Dr. Santosh Gowda says that 90% of
people, who develop cancers, do not have a family history. This
means that there is a mere 10% chance
of developing a cancer from a blood relative with the same DNA
composition. While the genetic factor
plays a minor role in one’s lives, the other elements that
increase the risk of developing cancer are:
the excess use of tobacco, alcohol, cigarettes, unhealthy diets,
intake of processed foods, practice of
unsafe and unprotected sex as well as the exposure to excess
ultraviolet radiation.

What are the types of cancer?
Cancer can affect literally every part of the body. So the types
of cancer have become uncountable.
Surprisingly, in India, 30-40% of the patients come under the
face and neck cancer issues when
compared to 2-3% in the US and Europe. This is attributed to the
large number of tobacco and betel
leaf chewers. Smoking is also a contributing factor but not so
much as tobacco. The reason being the
presence of areca nut, a toxic ingredient that is present in
most pan masala packets. However, the
saddening fact is that people are ignorant of its harmful side
effects, making it the number one reason
for mouth cancers.
The other frightening type is the blood cancer, otherwise known
as leukemia. The doctors at Narayana
Health repeatedly mention that leukemia is no more a death
sentence type of cancer, but can be cured
with the help of the latest medical advancements. Bone marrow
transplant is becoming an
increasingly common treatment option for leukemia patients. A
bone marrow donor can donate
his/her white blood cells to an active leukemia patient. The
patient’s WBC is replaced by injecting asubstance that will
stimulate the growth of the donated cells. The donor’s WBCs are
then used to
change the cancer patient’s blood structure as well as their
immune system. Owing to this advanced
mechanism, the process has resulted in a higher survival rate
among kids and adults of up to 60%.
But it’s also important to understand that the chances of a
leukemia survivor to easily relapse are very
high. As cancer of the blood deals with a fluid system, the
presence of even one cancer cell somewhere
in the blood system, can spread again bringing back the disease
to its fullest form. But, if a cancer
patient has crossed the five-year survival mark, then chances of
a relapse are rare.
Treatment options
Chemo, surgery and radiotherapy comprise the trinity of cancer
treatments. While medicines and
vaccines are an option for the treatment, they play a minor role
in bettering the patient’s condition.
Globally, chemo is the most effective option in most types of
cancers. In the past, chemo was used to
avoid death. But with recent developments such as bone marrow
transplant and stem cell transplant,
treatments seem to cure cancer. .
Prevention
Needless to say, a healthy diet, especially plenty of fruits and
vegetables, will help boost the immune
system and fight diseases. Plus, lots of exercise and a peaceful
mind will help you not only prevent
cancer but also help eliminate other diseases or health issues
and improve the overall quality of life.
Are there any good cancers?
As strange as it may sound, there are a few good types of
cancers. The term good here refers to a
complete cure. Cancers such as thyroid is a favorable cancer,
because the cure rate is almost 99%.
However, if the stage is advanced, then more aggressive
treatment is required. Likewise, Hodgkin
lymphoma can be cured up to 50-60% even in its advanced
stages.

Are stage 4 cancers really the end?
In most cancers, yes. Although N stage is terminal stage cancer,
testicular cancer and lymphoma are
exceptions. These two types can be cured and patients can
continue to live a normal life afterwards.
Doctors admit that stage 4 cancers cannot be cured. However, the
focus leans more towards
palliation-to extend their lifespan of the cancer patients and
alleviate their symptoms. Treating stage
4 cancers is not only about the chemo or radiation, but focusing
more on the quality of life.
Finally, to avoid the chances of getting cancer, put an end to
living an unhealthy lifestyle and switch
to a more active lifestyle, nutritious diet for a healthier
well-being. Watch the full Length webinar at
