We all fear cancer. And there is a good reason for that – in some cases, only early diagnosis may give us hope that a fight with a tumor will be successful. However, we are often confused as for detecting the early signs of cancer. What could they be? After all, there are many types of cancer out there, with different ways of development and cancer symptoms. Should we just give up then and wait for our fate? Not at all. While some early signs of cancer may be hard to spot, others are quite visible and once we learn them, we may have a higher chance of an early diagnosis.

Nowadays, when many Western countries suffer from the epidemics of overweight and obesity, and other countries follow this example, the increase in overweight-related diseases became an alarming reality. Still, many overweight people are not aware that not only their bones, joints and vascular system are at stake. If we ask an average person ‘does obesity increase cancer risk?’, the answer will be probably ‘no’. Unfortunately, we have some bad news: obesity or even being overweight does increase the cancer risk. Moreover, many common types of cancer are directly or indirectly caused by extra kilos.

What is cancer? This seemingly simple question would make a lot of people think a lot once they were asked it. While, due to changing environment and ageing of societies, we meet more and more people who undergo  therapy, we often have no idea what is it, apart from the fact that it is deadly or harmful to our body. Every effort to educate about causes, prevention, and treatment seems then a reasonable one and we will attempt to fill out information gaps in those of you who wonder a lot about it but are afraid to ask for basics or have a hard time looking it up online.

What causes cancer? There is no easy answer to this question. People leading a healthy lifestyle may get cancer while others with an unhealthy diet, smoking habit and other possible causes of cancer constantly present in their lives, may live long and happily. Cancer cause is sometimes thought to mean a ‘direct cause of cancer’. It is true to some extent for specific cancer causes but for many others, they only slightly increase the danger.
