Cervical Cancer is a type of
cancer that starts as abnormal tissue growth around the cervix, briefly before
spreading throughout the body hampering normal functioning. It can be diagnosed
in early stages and detected by having cervical screenings like the pap test,
or the cancer may spread in the uterus showcasing symptoms like abnormal
vaginal bleeding, back pain etc.
Also, it is the most common
cancer found in women, comprising up to 90% of all women's cancers. Generally
it is caused by the HPV virus, which anyone can get infected by various
reasons, including but not limited to: sexual contact with many individuals,
use of birth control, weak immune system etc. However, not all women infected
by HPV get this type of cancer. Early and effective treatment has surged the
5-year survival rate in US to 68% with a combined use of radiotherapy,
chemotherapy and surgery.
Signs and Symptoms
There may not be many
indications of it in early stages but once the cancer surfaces and starts to
multiply in the vaginal canal, there are a handful of signs and symptoms that
can be an alarming bell :
●
Abnormal vaginal bleeding
●
Mass discharge from vagina
●
Discomfort while sexual intercourse
●
Pelvic Pain
Symptoms of a rapidly growing
cervical cancer may include weight loss, nausea, leg pain, swollen legs, heavy
vaginal bleeding and rarely, it may also cause feces leakage from the vagina.
Causes and Prevention:
The most common cause of
cervical cancer in women is HPV or the human papillomavirus, while smoking,
using excessive birth control and having multiple pregnancies are also factors
known to cause cervical cancer.
HPV is known to contribute to
90% of cervical cancers in the world, however it is worth being informed that
not all HPV infections result in a cancer.
Out of 150-200 types of HPV
known to medicine, HPV 16 and 18 cause about 75% of all the cervical cancer
cases. These cases can be easily prevented by a HPV vaccine that targets the
two papillomavirus classes.
Other prevention techniques aim
at educating women to quit smoking, taking a balanced diet and encouraging them
to practise safe sex.
Family planning can also reduce
the chances of getting the cancer, as researchers found out in many studies
that women who had more (7 or more) full-time pregnancies had four times the
risk of developing the cancer as compared to women with no pregnancies and
two-to-three times the risk when compared to women with two or more full-time
pregnancies.
Treatment:
Treatment of a cancer usually
depends upon the stage at which it is detected, if detected early the cancer
can successfully treated. Age, health and quality of living are crucial aspects
to the treatment.
There are four types of
treatment to cervical cancer, they are:
● Surgery may be performed to remove the
cancerous tissues, keeping in mind patient desire to have children in the
future. To ensure such conditions, fertility sparing surgeries are performed.
● Radiation therapy weakens the cancerous cells
through high-dose radiation in the vaginal cavity. They are removed through
surgery afterwards.
● Chemotherapy This type of treatment is
usually used in very late stage cancer types, using medicines that target
cancerous cells and weakens them.
● Chemoradition is a mixed use of chemotherapy
and radiation therapy, which is used in middle to late stage cancers.
After evaluating and detecting the type, stage and condition of
the cancer, medical professional studies the case and offers a treatment option
which seems more feasible than others.
Success rate is 100% for women
with emergence form of cancer, but drops to 90% 5-year success rate for women
with Stage 1, subsequently dropping to 75% and 30% for women with Stage 2 and
Stage 3 cancer. Stage 4 cancer leaves the successful treatment rate to 15%, as
the cancer has already spread in the vaginal cavity, disrupting normal cellular
activity.
