Cause of colon cancer might not be what we thought

The cause of colon cancer might not be dietary or just hereditary. New research suggests polyps of the colon that lead to colon cancer could be caused in part by two specific types of  bacteria.
The finding has implications for how colon cancer begins and could mean new ways to prevent the disease that is the second leading cause of cancer death in the United States. (1) Two types of bacteria play role in inherited and sporadic colon cancerResearchers at Johns Hopkins made the discovery that two types of bacteria play a "critical role" in the development of  hereditary and sporadic cancer of the colon, based on observations that people with colon cancer harbor two types of intestinal bacteria.
The finding is also supported by studies in mice.

Why are these 2 skin cancers becoming more common in younger people?

Two types of skin cancer are becoming  more common; one  among women age 30 to 49.  You’ll want to know what to look for, but more importantly how to avoid a trip to the dermatologist that could result in bad news, stress and possibly surgery.


Squamous and basal cell skin cancer develop over time

These two types of skin cancer, squamous and basal cell take time to develop. If you’ve used tanning beds in the past or spent too many summers in the sun as a child, you could be at risk.


The bad news about what researchers recently found is you don’t have to be ‘older’ to develop skin cancer that, in the early stages,  may barely be noticeable or on a skin area that you don’t see every day.


The good news is that by being proactive with sunscreen or protective clothing even on cloudy days and having regular skin checkups you can lower your risk and get early treatment for what may have already occurred.  


Skin cancer is also, almost always, treatable and even more so in the early stages. The longer you wait to have a suspicious area examined - and if it is skin cancer - the more involved the procedure might be.


Squamous cell skin cancer tends to grow larger; is more invasive and can potentially spread to the lymph nodes and causes more discomfort than basal cell carcinoma.







Researchers from the Mayo Clinic highlight the prevalence of the skin cancers from the years 2000 to 2010 that they compared to 1976-1984 and 1985-1992.


Basal cell skin cancer increased in women age 3i0 to 49; squamous cell cancer is now more common in women 40-59 and 70-79.


Men had a slight decline in squamous cell skin cancer from 2000 to 2010, according to the finding, published in Mayo Clinic Proceedings. Prior years studied showed the skin cancer had been on the rise.


Men over age 29 also had the same increase in basal cell carcinoma as the previous periods.


Christian Baum, M.D., a Mayo Clinic dermatologist and the study’s senior author said in a media release: “This skin damage accumulates over time and can often lead to skin cancer.”


Information about the importance of sunscreen has been available for years, but Baum said tanning beds emerged in the 1980’s and “tanning…. was a common activity for many years”  in tanning beds and out of doors.


The message Baum wants to share is that sunburn and UV exposure damage occurs over time.


Maybe you’ve been faithful about avoiding sunburn and wearing your sunscreen for the past few years, but “eventually those blistering sunburns of your youth and hot, reddened skin, and peeling shoulders of your adulthood can add up to one or more skin cancers,” Baum said.

Skin cancer popping up in different areas of the body


Another finding from the study is that skin cancer is becoming more common on the head and neck.

The new study finds more people being diagnosed with basal cell tumors on the torso and  squamous cell skin cancer on the arms and legs.
