According to the World Cancer Report, in 2018, there were an estimated 1.16 million new cancer cases, 784,800 deaths due to cancer, and about 2.26 million prevalent cases. If we see it globally, according to the 2019 estimation, about 18.1 million new cancer cases have been added. The WHO report says, one among 10 Indians will fall prey to this deadly disease. And, one in 15 persons will die of cancer during their lifetime. This is literally horrifying. The underlying causes of cancer, however, can be attributed to multiple factors such as genetic, constitutional characteristics of the person, and in some cases environmental.
Cancer is referred to as the uncontrolled growth of abnormal cells which ultimately destroy the normal tissues of the body. The cancerous cells have the ability to spread throughout the body that in most cases leads to death. Even though cancer is the “second leading cause” for deaths globally, technological development and advancement in cancer screening & treatment have improved the survival rates to a greater extent.
Cancerous cells usually appear in a particular area in our body and then they spread throughout the body via lymph nodes. Some cancers form tumors that are visible while some don’t. Cancer can occur in different parts of the body such as skin, muscle, blood, bone, lungs, kidneys as well as the immune system.
The substances or things that cause cancer are called carcinogens. There are various kinds of carcinogens such as chemical substances like those present in tobacco smoke, and genetic, viral as well as environmental factors.
There is no single cause for the occurrence of cancer. As discussed earlier, there are multiple factors that can interact together to develop a cancerous growth by accumulated damage to cells or genes. The causes of cancer can be genetic such as family history for the disease, environmental such as emf exposure as well as the individual’s constitutional characteristics. We can group the risk factors or the causes of cancer as given below –
Wireless communication devices that we use in our day-to-day life such as mobile phones, laptops, computers, smart TVs, wifi routers, and other IoT devices, etc. emit electromagnetic radiation (EMR). This low-frequency, non-ionizing radiation emitted by all these gadgets can damage cells in the body. In 2011, IARC, a WHO agency, has classified radiofrequency electromagnetic field (RF-EMF) generated by EMR-emitting gadgets as “possibly carcinogenic to humans”.
This particular radiation-related risk factor, one of the major causes of cancer, can be negated by using certified radiation protection products.
It’s observed that certain types of genes experience mutation in certain types of cancers and 90% of cancers are reported to have some kind of genetic alteration (mutation). As per the studies to date, we have three main types of genes that experience mutation and affect the growth of cells.
