Impact of Radon Causing Lung Cancer
We all know that smoking kills, but what many don't realize is that it is exposure to Radon that causes the lung cancer that inflicts most smokers, and is the single greatest factor of lung cancer in non-smokers. The US Environmental Protection Agency and the Office of the Surgeon General have estimated that radon causes as many as 20,000 lung cancer deaths each year. Lung cancer induced by Radon costs over $2 billion dollars every year in direct and indirect healthcare costs.
What is Radon?
In layman's terms, Radon is a radioactive gas that causes cancer. Though Radon traces might be present in your home, you cannot see, smell or taste it.
If you smoke and your home has high levels of radon, your risk of developing Lung Canceris very high. Children are more sensitive to Radon because of their high respiration rate and rapidly dividing cells. They are more vulnerable to damage caused by radiation.
The US EPA says that 1 in 3 homes that were checked in seven states had Radon screening levels of over 4 pCi/L, which is the recommended level for safe Radon exposure. Though there is no "safe level" for Radon exposure, it is agreed that the risk of death due to Radon at 4 pCi/l is approximately 1 in 100. The alpha radiation that Radon emits is the same as that emitted by radiation sources like Plutonium.
The statistics are terrifying. If a home has radon levels of 4 pCi/l or greater, it is equivalent to the family being exposed to 35 times as much radiation as allowed by the National Regulatory Commission, if they were standing next to a fenced radioactive waste site. A school student spending 8 hours per day in a classroom with 4 pCi/l of Radon receives almost 10 times as much radiation as allowed at the edge of a nuclear power plant.
How does it get to us?
Radon occurs naturally as a radioactive gas, it comes from the natural breakdown of Uranium. The radio active decay of Uranium causes Radon to be present in igneous rock and soil, and even in water in some cases.
Humans are exposed to Radon through ingestion and inhalation. Radon that is present in the ground, water or building materials can enter living and working spaces and disintegrate. High radon concentrations in groundwater can contribute to exposure through ingestion, but inhalation of radon as it is released from water is typically more important.
Testing for Radon
Testing for Radon is the only way in which you can know the Radon levels present in your home. You can hire someone to get your home tested for Radon; there are also simple test kits for about $20 that are available at hardware stores. These kits are normally to be placed in the lowest living area of the home; they should be left in place for a few days and then sent to the manufacturer who then reports back with a radon level reading.
Questions and Answers
Cancer translational research brings together scientists' and clinicians' suggestions to develop solutions to biomedical complications. This kind of applied research strives to offer strategies to questions surrounding the etiology, pathology, diagnosis, prevention and treating cancer.
Orbs are actually a lumpectomy or quadrantectomy combined with rotating the breast tissue or mobilize the flap into the cavity of the surgery time fill is removed. It also includes the comparative change in shape and size is doing in relation to breast and moved if necessary, does not affect the conversion of the breast. The deferred plan the reconstruction is not part of endoplasmic techniques. Both procedures are performed by specific thoracic surgeons.
What every woman fears for is losing her self confidence , losing hope and losing her personality. The term "Breast Cancer" is a very negative word and that it creates negative vibrations in her heart. So, to make her comfortable with the basics of breast cancer and to make her means any woman understand that this type of cancer is the least dangerous than all cancers and that if it is detected early then you will fight with it successfully. Causes, Symptoms, treatment, discussed in detail.
Mesothelioma is a rare cancer that originates in the mesothelium. The mesothelium is the protective lining that covers the body's internal organs. Mesothelioma occurs when the mesothelium cells start to divide uncontrollably.
Chemotherapy is a treatment for killing cancerous cells which is given intravenous or extra-venous to the cancer patient. Even breast cancer patients have to go through the treatment. This treatment mainly focuses on the cancerous cells that are spread in the blood stream in the whole body . If any cancerous cells are there then they are killed by the chemotherapy medicine. The medicine is very costly and it has to be taken for one or two days continuously for every 21 days .
Malaysia has always been one of the most preferred tourist spots of South East Asia. Now, the country is becoming increasingly popular for another kind of tourism – medical tourism. Every year several thousands of medical travelers come to the state-of-the-art hospitals of Malaysia to be treated for various ailments, and recuperate in calm, scenic natural surroundings including beaches.
Cancer is a disease that causes cells to divide uncontrollably and even attack surrounding cells. Cancer cells are capable of spreading from the site of origin to other parts of the body via the blood and lymph system.
Modern healthcare services have improved a lot more than what they used to be just a few years back. Patients today are well educated and very much aware of every new development in the field of medicine, thanks to advanced technologies and the Internet.
Cancer is a dreaded disease. It makes its appearance as harmless symptoms and by the time the doctors make a definite diagnosis, it may have reached an incurable stage. Cancer treatment is very complex and expensive, as well as strenuous on the body and mind.
Cancer is a term denoting a number of diseases and not a single disease in itself. The common trait among all of them is that they cause the cells in the body grow and divide in an anomalous pattern and form tumors.
