How does cancer start? How do carcinogens in the environment set off the chain of events that eventually leads to cancer? According to Dr. Jason Fung, cancer starts with damage inflicted by some type of carcinogen. Sometimes the body fixes that damage incorrectly, causing slight changes in the genetic material—in other words, mutations. From there, evolutionary pressure drives cellular reproduction. Keep reading to learn about the origins of cancer, according to Dr. Fung.

How does cancer spread to other parts of the body? Is there a way to prevent cancerous cells from migrating and invading other organs? When cancer spreads to other parts of the body, it’s called “metastatic cancer.” In order to metastasize, cancerous cells must travel to other parts of the body through the bloodstream. According to Dr. Jason Fung, this process happens in cycles because the immune system will mount its defenses to prevent cancerous cells from spreading. Here’s how cancer metastasizes and invades other organs.

How close are we to curing cancer? What are some promising therapies for treating cancer? We’ve come far in our understanding of cancer, resulting in a number of promising treatments with fewer side effects. In fact, we may be nearing a turning point in the way we treat cancer. Here’s a look at promising future cancer treatments.

What exactly is cancer, and why is it so hard to treat? Why is cancer so prevalent? How close are we to eradicating cancer? Cancer is one of the most frightening diseases in the world today. It’s deadly and often extremely hard to cure. As such, doctors and researchers have spent enormous amounts of time and money trying to figure out exactly what cancer is, how it works, and how to cure it. In this article, you’ll learn about the progress we’ve made toward our understanding of cancer.

Can cancer be passed down genetically? To what extent is cancer hereditary? And if bad genes don’t cause cancer, what does? Contrary to a common misconception, cancer can’t be directly passed down to offspring (although various genes do make certain types of cancer more likely). According to Dr. Jason Fung, cancer is almost always the result of environmental factors called carcinogens—literally, “tumor creators.” Here’s how carcinogens cause cancer and drive its growth.
