These are the 21 genius cancer breakthroughs scientists want you to know about.
Blood in the stool

Cases are increasingly common in people under the age of 50—the age at which colon cancer screening is typically first recommended—Dr. Wender says it’s important to get checked out. “It’s easy to dismiss it as hemorrhoids or constipation, and if the problem comes and goes, people reassure themselves that nothing’s wrong, especially younger people,” he says. “But blood in a bowel movement is never normal, so get it checked out.”
Noticeable skin changes

Thomas Skin cancer is the most common cancer in America, but it’s also one of the trickiest to recognize the early signs, says Dr. Wender. “Skin cancer is a tough one—many people think freckles, moles, or a darker age spot is just like the others they’ve had,” he says. Dr. Wender says if you notice a mole getting darker, larger, or becoming raised, get it checked out. Melanoma skin changes are easier to identify because those spots are often irregularly shaped as opposed to round, significantly darker in color, or even two distinctly different colors within one spot, he says. “Melanoma is far less common than other skin cancers but has the potential to be more deadly,” says Wender. “However, many melanomas have a long period where they’re not invasive and easy to cure, as long as they’re caught early.” These are sneaky places you didn’t realize you can get skin cancer.
