Why Is Colon Cancer Increasing In Young Adults?

Author: Dr. Stephen Chaney


colon cancer intestinesA recent study on colorectal cancer reminds me of that famous Dickens quote: “It was the best of times. It was the worst of times.”

The good news (best of times) is that colorectal cancer rates in the United States have been declining for several decades for adults over 50. The decline is attributed to a healthier lifestyle and better screening.

The bad news (worst of times) is that colorectal cancer rates are increasing at an alarming rate for young adults. We have also learned recently that heart attacks are increasing for young women.

These studies are a wake-up call. We need to be asking:

  • Why are young people in our country dying from diseases that we traditionally associate with older adults?
  • What can we do about it?

How Was The Study Done?

colon cancer studyThis study (RL Siegel et al, Journal of the National Cancer Institute, 109 (8): djw322, 2017 ) was an analysis of data collected between 1974 and 2013 from a registry of cancer diagnoses called the Surveillance, Epidemiology, and End Results (SEER) Program. The data were collected from nine regions of the United States (Atlanta, Connecticut, Detroit, Hawaii, Iowa, New Mexico, Seattle-Puget Sound, San Francisco-Oakland, and Utah).

In this study 490,305 patients 20 years and older developed colorectal cancer between 1974 and 2013. This study divided those colorectal cancer cases into 11 age groups (20-29, 30-39, 40-49, 50-54, 55-59, 60-64, 65-69, 70-74, 75-79, 80-84, and 84+). The study then compared colorectal cancer rates for each age group in 8 five-year time periods (1974-1978, 1979-1983, 1984-1988, 1989-1993, 1994-1998, 1999-2003, 2004-2008, and 2009-2013).

What Did The Study Show?

colon cancer increaseWhen the investigators looked at the change in colon cancer incidence over time in different age groups, the results were quite alarming.

  • For adults age 20-29 colon cancer rates increased by 2.4% per year between the mid-1980s and 2013. While that doesn’t sound like much, 2.4% per year adds up. Colon cancer rates almost doubled between 1985 and 2013 for that age group.
  • For adults age 30-39 colon cancer rates increased by 1% per year over that same time period. That’s a 25% increase between 1985 and 2013.
  • By the mid-1990s colon cancer rates started increasing by 1.3% per year for the 40-49 age group and 0.5% per year for the 50-54 age group.
  • The only good news was that colon cancer rates continued to decrease for adults aged 55 and above.

When the investigators looked at the change in rectal cancer incidence over time in different age groups the results were even more alarming.

  • For adults age 20-29 rectal cancer rates increased by 3.2% per year between 1974 and 2013. That’s an almost 4-fold increase in rectal cancer for that age group.
  • For adults age 30-39 rectal cancer rates increased by 3.2% per year between the mid-1980s and 2013. That’s about a 3-fold increase.
  • By the 1990s rectal cancer rates started increasing by 2.3% per year for the 40-49 age group and the 50-54 age group.
  • Once again, the only good news was that rectal cancer rates continued to decrease for adults aged 55 and above.


Why Is Colon Cancer Increasing In Young Adults?


whyThis study is a clear wake-up call. If colorectal cancer rates are increasing so dramatically in young adults, it does not bode well for them once they reach their 60s, 70s and beyond. This is an impending health crisis. We need to ask:

  • Why this is happening?
  • What can we do about it?

The simple answer to the first question is that no one knows for sure why colorectal cancer incidence is increasing in young adults. However, here is what experts think might be happening:

  • Obesity is a prime suspect. The increase in colorectal cancer incidence in young adults closely parallels the obesity epidemic, and obesity is associated with an increased risk of colon cancer.
  • Many of today’s most popular diets may just make matters worse. Fad diets promise rapid weight loss, but they may also increase the risk of colorectal cancer.
  • Fad diets often restrict fruits, grains, and/or legumes. Plant based diets containing lots of fruits, vegetables, whole grains, and legumes are associated with a significantly lower risk of colorectal cancer. We have no evidence that we can leave out any component of a plant-based diet and still reduce colorectal cancer risk to the same extent.
  • Fad diets often emphasize red meat as a protein source. The World Health Organization considers red meat as a probable carcinogen. The association between red meat consumption and cancer incidence is stronger for colon cancer than for any other cancer.
  • Fad diets are often high in saturated fats, and saturated fat is associated with an increased risk of colorectal cancer.
  • Finally, fad diets are often low in fiber. Low fiber diets alter our microbiome (gut bacteria), and recent research suggests our microbiome may play an important role in preventing colon cancer.
  • The typical American diet is no better. It is high in red meat and saturated fats. It is low in fruits, vegetables, whole grains, legumes and fiber. Plus, it is high in sugar, sweets, and refined grains. With respect to colorectal cancer risk, it is the worst of all possible worlds.
  • We don’t get enough folic acid, calcium and omega-3s in our diet. Those nutrients are associated with a lower risk of colorectal cancer.
  • We don’t move enough. A sedentary lifestyle is also associated with an increased risk of colorectal cancer.
  • Cigarettes and alcohol are associated with an increased risk of colorectal cancer. However, smoking and alcohol consumption have been declining in recent years, so they do not explain the increase in colorectal cancer we are seeing in young adults.

In summary, the authors of this study concluded: “These results highlight the need for…research to elucidate causes for the…increase in disease risk in young [adults], as well as creative new strategies to curb the obesity epidemic and shift Americans towards healthier eating and more active lifestyles.”

Colon Cancer Prevention


colon cancer fruits and vegetablesIf you are a young adult, you are probably wondering what you can do to reduce your risk of colorectal cancer. The good news is that we have a good idea of how to reduce the risk of colon cancer, and it works at any age.

Let’s start with the American Cancer Society recommendations  for decreasing the risk of colorectal cancer. They are (with direct quotes from The American Cancer Society in quotation marks):

  • Get screened for colorectal cancer. The American Cancer Society recommends that screening start at age 45. However, you may want to consult with your doctor about earlier screening if you have a family history of early-onset colon cancer, have blood in your stool, or develop bowel changes that last more than a few weeks.
  • Eat lots of vegetables, fruits, and whole grains. According to the American Cancer Society: “Diets that include lots of vegetables, fruits, and whole grains have been linked with decreased risk of colon or rectal cancers.”
  • Eat less red meat and processed meats. They “have been linked with an increased risk of colorectal cancer.”
  • Get regular exercise. “If you are not physically active, you may have a greater chance of developing colon or rectal cancers.”
  • Watch your weight. “Being overweight increases your risk of getting and dying from colon or rectal cancer.”
  • Don’t smoke. “Long-term smokers are more likely than non-smokers to develop and die from colon or rectal cancer.”
  • Limit alcohol. “Alcohol use has been linked with a higher risk of colorectal cancer.”


Other experts recommend:

  • Limit saturated fats. Replace saturated fats with monounsaturated fats and polyunsaturated fats.
  • Get plenty of fiber. That should be no problem if you are consuming a primarily plant-based diet containing lots of fruits, vegetables, whole grains and legumes.
  • Make sure you are getting enough folic acid, calcium, and omega-3s. I recommend supplementation because even healthy diets often fall short of these nutrients.

I would add one final recommendation:

  • Avoid fad diets that take you away from a healthy eating pattern (described above), one that is known to reduce colorectal cancer risk.


The Bottom Line


A recent study has reported an alarming increase in colorectal cancer incidence in young adults.

  • For adults in the 20-29 age range, colon cancer incidence has increased 2-fold and rectal cancer incidence has increased 4-fold over the last few decades.
  • Colon and rectal cancer incidence have also increased significantly for adults in the 30-39 and 40-49 age groups.
  • The only good news from this study is that colon and rectal cancer incidence is continuing to decline for older adults.

This is a clear wake-up call. If this trend is not reversed, it does not bode well for these adults when they reach their 60s, 70s, 80s, and beyond.

What Is The Pectineus Muscle And Why Is It Important?

Spring Is In The Air

spring floridaI remember as a child we sang “Though April showers may come your way…they bring the flowers that bloom in May…”

Of course, here in Florida we are blessed with flowers all year, but there’s still a lovely feeling that happens in Spring.  It’s still cool enough most days to go out running, and the humidity is still low.  Traffic will soon be easing up as our friends from the north start their trek back home, and daylight savings time is giving us more time to get to the beach for sunset.  Lovely!

Fun Facts About Spring….

  • The earliest known use of the term “spring cleaning” was in 1857
  • The word “spring” has been used for the season since the 16th century
  • The first day of spring is called the vernal equinox
  • On the first day of spring, the sunrise and sunset are about 12 hours apart everywhere on earth
  • Spring fever isn’t just a saying. Experts say the body changes due to the temperature and can cause an upset in your health.
  • The actual start of spring varies from March 19th to the 21st, but it is commonly celebrated on the 21st.

Do you like to garden?  Now is the perfect time to get your gardens planted so you’ll have home grown veggies for the entire summer.  For me, it’s also a great time to do some spring cleaning and get the house in order before the summer closes all the windows and the air conditioning becomes our indoor relief.

But these activities can also cause a strain on muscles, so don’t forget to take care of yourself. If you put too much strain on muscles you haven’t used all winter, you can develop problems and need groin pain relief.


A Tiny Muscle Can Cause Groin Pain

groin pain relief pectineusLately I’ve had several clients come in because of groin pain that has their medical practitioners stumped.  Their symptoms are varied, but most complain that it feels like they hit their pubic bone with a rubber mallet.  Ouch!

One client loves to ride her horse, but the pain had prevented that for several weeks. Another was considering selling the motorcycle that she and her husband love because she just can’t sit on it anymore.

Several years ago, I had a male client tell me that he had this same pain and he was told it could be his prostrate causing the issue.  Fortunately, that wasn’t he problem at all.

The muscle that caused all these problems, and a lot more, is the Pectineus.

The Pectineus muscle originates on your pubic bone and inserts into the very top of your inner thigh bone (femur).

You can see the Pectineus and surrounding muscles more clearly by going to

Most muscles have more than one function, and this is true for the Pectineus.  The function we’ll look at today is called adduction.  It brings your leg in toward midline.  If you think of a soccer player kicking the ball with the inside of his ankle, it was the Pectineus that helped draw his leg in so he could do the shot.

Each of my clients had pain while trying to bring their leg out so they could sit on their horse, or on their motorcycle.  The tight muscle was pulling on their pubic bone and causing a severe strain.

This muscle is easier to have someone else treat it for you because of its location but give it a try and see if you can locate & treat it yourself.

To reach the Pectineus, move the ball all the way up to the crease in your leg.  You can do the treatment with a ball, but because of the size of the muscle and its location, it’s easier to do it with your fingertips.

Sit as this athlete is sitting, and even bring your opposite leg up so your foot is flat on the floor.  For example, in this picture, the athlete would bring her right leg up so her right foot is on the floor, and then lean a bit further onto her left hip.  That opens up the area so she can reach a bit easier into the muscle while using her fingertips.

Press into the muscle, being careful to feel for a pulse, and moving if you feel one.  If the Pectineus is in spasm, you’ll know it immediately when you press on it.  If it’s not in spasm, you won’t be able to find it at all.

Remember to stay within your pain tolerance level, this isn’t a “no pain, no gain” situation.  Never go deeper than what feels tender, but not so much that you want to faint. Hold the pressure for 15 seconds. Then let up on the pressure, but keep your fingers in the same place.

Repeat this movement several times. Each time it will hurt less, and eventually it won’t hurt at all.  That’s when the muscle has completely released, and you will have relief from the pain.

It’s as simple as that!

Why stay in pain when it’s so easy to find the muscular source of the problem and eliminate it?
