More and more cancer types are being linked to air pollution. While the linkage is quite easily understandable between air pollution and lung cancer, the damage does not stop there. It is far more harmful, and whether or not it is part of the respiratory system, most cancers are linked to air pollution. The World Health Organization (WHO) has classified air pollution as carcinogenic to humans.
The amount of particulate matter in the air, especially in developing countries like China and India, are loaded with carcinogenic material. This is due to increased transport overload, power generation, industrial emissions, residential heating etc. The exact composition of the air can vary depending on the time of the year, the location, weather, etc. The International Agency for Research on Cancer (IARC) also is spending a lot of time and money to find out the connection between these two. Establishing the link can help in preventing cancer.
Read on to understand the correlation between factors affecting air pollution and cancer incidence.
- Air pollution is not uniform and varies across the globe, depending on how some of the above mentioned factors are affected.
- Developing countries have more pollution levels, especially from vehicular fuel exhaust, metals, dust, and chemical solvents. These contaminate the air, making it carcinogenic.
- There is also lead, which is another “probable human carcinogen,” causing cancer of the liver, brain, and kidney.
- The other chemicals in polluted air include sulfur dioxide, nitrogen oxide, carbon monoxide and ozone.
- Also there are various compounds like volatile organic compounds, outdoor air pollutants, and other particulate matter, which are present in greater numbers in polluted areas.
- Paint thinners, dry cleaning agents, and other metals also contribute to increased air pollution. This, when inhaled, induces chronic inflammation in the tissues, making them react to the inflammation.
- Both outdoor and indoor agents cause pollution, and increases risk of developing cancer.
- Second hand smoke is a lot more dangerous than imaginable in inducing cancer.
Mechanism: Cancer is a result of chronic inflammation, which induces uncontrolled proliferation of the cells. A combination of the above mentioned compounds along with a strong predisposition (family history, for instance) puts the person at a very high risk to develop cancer. The symptoms may takes years, sometimes decades, to develop, but the onset starts off with continued exposure to these agents. So, if you are predisposed to developing cancer, ensure your exposure to the above pollutants is reduced, even if it cannot be completely avoided. If you wish to discuss about any specific problem, you can consult an Oncologist.
Cervical cancer occurs when abnormal cells on the cervix grow out of control. The cervix is the lower part of the uterus that opens into the vagina. Cervical Cancer is one of the most common ailments that women suffer from, making it only more important to be taken seriously and treated immediately.
Most cervical cancer is caused by a virus called human papillomavirus, or HPV. You can get HPV by having sexual contact with someone who has it. There are many types of the HPV virus. Not all types of HPV cause cervical cancer. Some of them cause genital warts, but other types may not cause any symptoms.
Most adults have been infected with HPV at some time. An infection may go away on its own. But sometimes it can lead to cervical cancer. That's why it's important for women to have regular screening. A screening can find changes in cervical cells before they turn into cancer. If you treat these cell changes, you may prevent cervical cancer.
Symptoms of Cervical Cancer may include:
- Bleeding from the vagina that is not normal, such as bleeding between menstrual periods, after sex, or after menopause.
- Persistent abnormal discharge.
Cervical cancer is the easiest gynecologic cancer to prevent, with regular screening tests and follow-up. Two screening tests can help prevent cervical cancer or find it early:
- The Pap test (or Pap smear) looks for precancers, cell changes on the cervix that might become cervical cancer if they are not treated appropriately.
- The HPV test looks for the virus (human papillomavirus) that can cause these cell changes.
When to Get Screened
You should start getting regular Pap tests at age 21. The Pap test, which screens for cervical cancer, is one of the most reliable and effective cancer screening tests available. The Pap test is the best way to find cervical cell changes that can lead to cervical cancer. Regular Pap tests almost always show these cell changes before they turn into cancer. It's important to follow up with your doctor after any abnormal Pap test result so you can treat abnormal cell changes. This may help prevent cervical cancer.
In spite of being a fatal ailment, over the years various treatments have evolved that deal with this problem effectively. Some of them are:
1. Surgery: One of the effective and oft availed treatment to cure cervical cancer is surgery. Depending on the stage on which the disease is detected, doctors may suggest for a hysterectomy or removing the pelvic nymph nodes.
2. Chemotherapy: This has emerged as the most sought after way of treating any form of cancer. The abnormal growth of cells that triggers cancer in the first place is deterred in this method by administering drugs to destroy them. If you wish to discuss about any specific problem, you can consult a gynaecologist and ask a free question.
My father got prostate surgery on 14/12/2016. Nowadays he is facing problem of constipation, is there any remedy for it, is it the side effects of surgery.
Let’s start with some mind-boggling statistics: in India, over 2.5 million patients are diagnosed with cancer. Moreover, it is estimated that around 700,000 new patients are found to have cancer, each year, and around 550,000 annual deaths are related to cancer.
While these perturbing numbers might unnerve you, there is, however, a case for cautious optimism. While there are certain causes of cancer like genetics and environment which are beyond your realms of control; there are certain causes which can be controlled by you. Research shows that nearly 70% of cancer causes are in your hands – including your own diet.
Your daily nutritional intake is vital for two reasons:
- There are definite cancer-preventing nutrients and food items;
- Conversely, there are certain types of nutrients and food items which cause cancer.
While research typically points to links between food items and cancer than well-established cause-effect relationships, it is found that certain dietary items have a greater influence. Here are some general guidelines to guide you better:
- Avoid processed and red meat: Processed and red meat are generally considered as any meat which has been artificially modified for taste or purposes of preservation. It must be noted that during this process of preservation there are certain chemicals mixed with it which makes it carcinogenic in nature. Though the WHO (World health organization) hasn’t recommended any specific amount for consumption, it has categorized processed and red meats as a Group 1 – carcinogen.
- Consume more fruits and vegetables: Plant foods including fruits and vegetables contain essential micronutrients like flavonoids and carotenoids which researchers’ state are powerful antioxidants. Antioxidants help prevent the destruction of cells as they diminish free radicals. It is recommended to regularly consume fruits and vegetables like berries, broccoli, leafy greens, apples, papaya, among others.
- Reduce your alcohol and smoking habit: Along with processed and red meats, alcohol is designated as a Group 1 – carcinogen by the WHO. Cancer research has repeatedly linked consumption of alcohol to higher chances of cancer, irrespective of the alcohol type. A number of cancers including pharynx, liver, and breast are directly connected to alcohol.
Furthermore, it is suggested that an individual must limit to no more than a drink on any given day.
In conclusion, it must be stated that our diets play an indispensable role in the prevention of cancer. The consumption of healthy food items will only bolster our physical well-being along with the reduction of cancer occurrence. In case you have a concern or query you can always consult an expert & get answers to your questions!
After the operation of brain cancer, there is any chance of further occurrence of brain cancer in same region again.
Cancer in colon forms due to uncontrolled cell growth in the large intestine cells. Most colon cancers originate from the healthy cells in the lining of the colon that grow into tumors called adenomatous polyps. These polyps can be cancerous or benign. A cancerous tumor is malignant and may spread to the other parts of the body by traveling through blood and lymph systems, this process is known as metastasis. Whereas a benign tumor can grow but don’t necessarily spread to other parts of the body. It takes years for these changes to develop depending upon both genetic and environmental causes.
Causes and risk factors:
In a healthy body, the cells normally grow, divide and then die. Cancer is the result of uncontrollable cell growth where the cells do not die. Aging is one of the important risk factors for colon cancer; other risk factors include a family history of colon cancer. As per Johns LE and Houlston RS individuals with a family history of colon cancer have a high risk of developing this form of cancer as compared to those with no such history. A study conducted by Giovannucci and others in 1995, successfully established the relation between physical activity, obesity and colon cancer. As per the research lack of physical activities elevates the chance of getting colon cancer. Individuals who regularly smoke, are obese and use aspirin have a higher risk of developing this form of cancer. Diet is also an important factor, diets that are high in fat and low in fiber may elevate the risk.
The symptoms of colon cancer are varied, depending upon the condition of the tumor. At the early stage, patients may experience no symptoms. However, as cancer grows, symptoms arise. Diarrhea or constipation are common; patients may see changes in stool consistency and narrower stool. Abdominal discomfort, bloating, fullness and cramps may also indicate colon cancer. Sudden weight loss and unexplained iron deficiency (anemia) are also associated with this form of cancer. If these symptoms last for several weeks, don’t hesitate to consult your physician.
Colon cancer is highly treatable and depends on the type and the stage of cancer along with health and other characteristics of the patient. However, there is no single treatment; the most common options are – surgery, chemotherapy and radiation therapy. The surgery for colon cancer is known as colectomy and involves removing the affected part of the colon and the adjoining areas including nearby lymph nodes. Chemotherapy involves killing the cancer cells by utilizing certain chemicals that interfere the cell division process and damage the proteins or DNA. In the radiation therapy, high-energy gamma rays are used to target and destroy the cancer cells. Radiotherapy can be used both as a standalone treatment and also along with other treatments.
