Even the word cancer is enough to instill feelings of dread and anxiety in most of us. The sad reality is that this is a disease that affects all of us in some way. We read and hear about cancer all the time. But what exactly is it, and what’s being done to try and save more lives?
What exactly is cancer and who gets it?
Cancer is one of the most common causes of death in the developed world. Every year in the US, more than 1.6 million new cases of cancer are diagnosed. More than half a million people die as a result of cancer every year, and that’s just in America. The statistics are frightening. But the good news is that more and more people are surviving cancer.
Cancer occurs as a result of abnormal cell division that arises from genetic mutations. This causes lumps, known as tumors, to develop. There are lots of different reasons why a mutation may occur. Sometimes, there are clear risk factors. In other cases, there is no explanation. Common risk factors for cancer include smoking, exposure to radiation, and obesity. In some cases, there also appears to be a genetic link. This means that you’re more likely to develop cancer if a close relative has cancer. Risk factors increase your chances of developing a certain form of cancer. However, you won’t always get cancer if you have risk factors. Likewise, it’s possible to develop cancer even if none of the known factors are applicable to you.
Many forms of cancer, including bowel, lung, and prostate cancer are more common in older people. Brain tumors, testicular cancer and leukemia are more prevalent in younger adults.

Cancer symptoms
There are more than two hundred different types of cancer, and symptoms vary hugely. However, there are some common warning signs. Examples include unexplained weight loss, lumps or abnormal swelling, and changes in bowel habits. If you experience any of these symptoms, it’s important to see a doctor. There’s a good chance that there’ll be nothing to worry about. But it’s best to be cautious.

Treating cancer and cancer research
There are various methods used to treat cancer. Often a combination of therapies is the most effective option. Currently, most patients receive treatments include chemotherapy, radiotherapy, and surgery. Doctors recommend treatments based on the type, stage and grade of cancer. This relates to how advanced the condition is, and whether it has spread. There are also other techniques available, such as immunotherapy and biological therapies.
Research into cancer treatment is ongoing. There have been major developments in recent years. Survival rates have increased thanks to new and improved treatments. Scientists all over the world are currently working on pioneering projects.

Cancer is a word that brings fear wherever it goes. Sadly, most of us are touched by cancer in one way or another. Survival rates are increasing all the time, but scientists are still searching for a cure.
