Unfortunately, the answer to this question is not so simple. Cancer is a disease which affects our body as well as our soul. It can arise anywhere in the body with differential and unpredictable behavior. Cancer in the head and neck region behaves very differently from the ones arising in the breast. No two cancers follow the same pattern, further adding to the list of challenges in managing this disease. This leads to the validation of the age-old fundamental concept of prevention is better than cure.
Unfortunately, the answer to this question is not so simple. Cancer is a disease which affects our body as well as our soul, it can arise anywhere in the body with differential and unpredictable behavior. Cancer in the head and neck region behaves very differently from the ones occurring in the breast. No two cancers follow the same pattern, further adding to the list of challenges in managing this disease. This leads to the validation of the age-old fundamental concept of prevention is better than cure.
As discussed previously, certain factors are modifiable, and if we improve our habits, we can certainly reduce the risk of developing cancer. Whenever we talk about cancer prevention, two common terms we come across are screening and early detection. Screening is merely testing apparently normal individuals who are at high risk of developing cancer. Early detection implies identifying cancer when it is still curable. Screening and early detection are of use if it detects cancer which is curable thereby improves survival. Currently, screening guidelines exist for breast cancer, cervical cancer, lung cancer, and colorectal cancer. To simplify, if these cancers are detected very early, one can be optimistic about the cure and a life span like healthy individuals.
It is the most common cancer in the world and our country. The lifetime risk of developing breast cancer in any female is 12.4 %. Nearly 90 % of breast cancer patients go beyond 5 years. As per latest data, 62 % of breast cancers are identified when they are still limited to the breast. Also, the death rates have been reducing at 1.8 % per year. This is possible only because of increased awareness among females, advances in treatment modalities, and reduction in treatment-related side effects.
Nowadays, many females themselves report to their doctor with a small lump in the breast. On most occasions, such lump is benign (a growth which is not cancer). However, it is worth evaluating to identify cancer. Following are the factors which are associated with increased risk of developing breast cancer:
There are risk assessment models available online, which gives an estimate of developing breast cancer in the next 5 years. A score of less than 1.7 % is considered as high risk. For females above 35 years of age, who are at high risk, there are certain screening test recommended, which help in detecting this cancer early and prevent the wrath of advanced cancer.
Uterus (womb) is a female organ in which the child lives during pregnancy. This uterus opens into the vagina, the part which extends into the vagina is called the cervix. This cervix is located approximately 6-7 cm from the vaginal opening. Cancers arising in the cervix are prevalent especially in developing countries like ours. As per the latest statistics, it is the 3rd most common cancer overall and 2nd most common cancer in females. The lifetime risk of developing cervical cancer in any female is 0.6 %. A female diagnosed with cervical cancer has approximately 65 % chance of survival beyond 5 years. However, this number goes beyond 90 %, if the cancer is limited to the cervix. Thus justifying the need for early detection.
The most significant association of the cancer is with human papillomavirus (HPV). Higher the presence of this virus, higher the risk of developing this cancer. There is an approximate 20 % chance that any female has this virus in her genital tract. Factors that can lead to increased risk of harboring HPV are early age are:
There is a very high probability that the females are associated with at least one of the risk factors mentioned. Thus it becomes important that all females should get themselves screened and help the community in fighting and winning against this cancer.
HPV vaccination is usually recommended for sexually inactive young girls aged 9 to 14 years, however for other age groups it can be considered. One should discuss with their doctor regarding feasibility and risk-benefit aspects. The major limitation in its widespread use is its cost.
Lungs are sponge-like organs in our chest which are responsible for providing oxygen to the blood which is then transported to the entire body. This oxygen is essential for most of the functions carried out by the body. Smoking reduces the elasticity of the lungs and deposits various hazardous chemicals in the lungs. This deposition of chemicals irritates the lung to an extent that the cells become cancerous.
Lung cancer is the third most common cancer-related deaths in our country with a lifetime risk of 6.2 % chance of developing this illness. Smoking is the single most common associated risk factor with this cancer. Tobacco smoking accounts for 85 % of cancer-related deaths. Smoking is estimated to cause about 30 % of deaths due to cancer. The risk for lung cancers is 20 times higher for smokers compared to non-smokers.
Reduction in deaths from lung cancer can be achieved with timely screening. Overall chances of survival beyond 5 years are only around 20 %. However, if the cancer is limited to the lungs, the chances are around 50 %. Thus it is very important to identify your risk status and do timely check up so that this cancer is detected early and still curable. If you satisfy the following conditions, then it is important that you get yourself screened for lung cancer:
The gastrointestinal tract is a long elastic tube which starts about 15 cm from the teeth and ends at the anus, the lowermost part between the buttocks. When we eat, the food passes through this tube and with the help of various chemicals called enzymes at different levels, the nutrients are extracted from that food whereas the remnant is passed as stools. The different parts of this tube are from the above esophagus (commonly called the food pipe), stomach, small intestine, large intestine (also called as the colon), rectum, and anal canal. There is a lot of similarity between colon and rectum, hence often they are clubbed as colorectum.
Cancers in the colorectal region are common and usually related to the type of food we eat and family history. The basic principle lies in the fact, longer the carcinogen (a substance that can result in cancer) is in contact with colorectum, higher the chances of cancer. Any food or activity that delays the motility and propelling activity of the colorectum is a harmful and potential cancer-causing agent.Important risk factors include:
However, these polyps have variable behavior ranging from simple non-cancerous turning to the dangerous ones which have a definite potential to become cancerous. The lifetime risk of developing this cancer is 4.2 %. The five year chance of survival falls drastically from 90% for localized cancers to under 15 % for the ones which have spread to the entire body. It is recommended that individuals should be screening for this cancer because the early diagnosis has a significant impact on survival, tested patients have a 44 % lower risk of developing this cancer, and for every 1 % increase in colonoscopy rate, there is 3 % decrease in deaths from colorectal cancer.
