Colorectal cancer is the second-deadliest cancer in the United States – largely because it goes undiagnosed. Dr. Christi Matteoni, Division Chief of Gastroenterology at Renown Health, discusses the symptoms and key screenings used to detect this type of cancer, along with risk factors and lifestyle changes that could affect the likelihood of getting the disease. What are some of the signs and symptoms of colorectal cancer?  Many cases go undiagnosed because polyps can develop and become cancerous without any symptoms. Additionally, since colorectal cancer begins as small polyps, symptoms usually aren’t seen until later stages. This is why screenings are especially important.  For those who do experience symptoms, the signs are often tied to your bowel habits. This can include changes such as constipation or diarrhea, narrow or dark stool, rectal bleeding, abdominal cramping, weakness and fatigue or unintended weight loss.  What are some of the risk factors associated with this type of cancer?  There are risk factors that can and cannot be controlled. Uncontrollable factors include age, race, personal and family histories as well as certain genetic syndromes that are important to discuss with your provider.  This type of cancer is more common in people over the age of 50, African Americans and those of eastern European Jewish (Ashkenazi) descent. This type of cancer is also more common in those who have been diagnosed with polyps, Crohn’s disease, ulcerative colitis and long-term inflammatory bowel disease. important to discuss any of these risk factors with your provider.  There are also lifestyle factors that can help reduce your risk. Factors include being overweight, having a diet high in red and processed meat, as well as smoking and consuming excess alcohol.  Conversely, diets high in fruits and vegetables and a regular exercise routine can help lower your risk.  If someone has some of these risk factors, what should they do? Do they need to get tested?  If you are 45 or older and have any of these risk factors, we recommend you speak with your primary care provider about a formal colorectal risk assessment.  The most common form of screening is colonoscopy. This screening lets your doctor examine the length of your colon, map out any potential problem areas and remove polyps. For most people, colonoscopies are recommended every 10 years starting at age 50. However, depending on your results and risk factors, you may need to begin screening sooner or get screened more frequently.  What do diagnosis and treatment look like for this type of cancer?  There are several diagnostic options for colorectal cancer, including endoscopic ultrasound; CT, MRI and PET scans; and biopsy and pathology reports. These technologies allow your doctor to get images of your colon and evaluate what treatment is needed, as well as how the treatment is progressing.  Treatment varies for each individual working with their doctor. In the case of colorectal cancer treatment, the William N. Pennington Institute for Cancer offers chemotherapy, radiation therapy, surgery and clinical trials.

You probably know testosterone (T) plays an important role in how boys physically develop into men. But is that all you know? What happens when a man's T levels are off? Are there symptoms men should look for? And what are the treatment options? Dr. Bobby Kahlon, MD, Renown Medical Group provides answers in a Testosterone Q&A.   What does testosterone do for men?  "Testosterone is known as the 'manly hormone' for a reason," says Dr. Kahlon. "Though women also naturally produce small amounts of it, men produce testosterone at much higher concentration levels. And it affects men in more physical and obvious ways. How much hair a man has on his chest, how deep his voice is, or how muscular he is are all attributable in some way to testosterone. It's also responsible in large part for sex drive and bone strength and affects how men think, learn and experience their surroundings."  Testosterone in men:   Powers virilization (male physical characteristics) and sexual function Builds muscle mass and strength  Supports bone density  Improves cognition  T Trivia: Discover Magazine reveals that “manly” testosterone and other sex hormones evolved long before we did — 500 million years ago — from the ultimate “female” hormone, estrogen. Can you have too much or too little testosterone?  Though high testosterone isn't a concern for most men, low testosterone or low T occurs more frequently and develops for two primary reasons.  Dr. Kuhadiya explains, "Subnormal testosterone concentrations occur either due to pituitary or testicular failure and the causes for each need to be discussed with your physician."  Pituitary failure: Approximately one-third of men with obesity, type 2 diabetes, or metabolic syndrome (which includes increased blood pressure, high blood sugar, excess body fat around the waist, and abnormal cholesterol or triglyceride levels) have low free — or "bioavailable" — testosterone. These health conditions can cause the pituitary gland to "fail" to release follicle stimulating hormone (FSH) and luteinizing hormone (LH) which are essential for triggering testosterone and sperm production. And that can cause low testosterone (hypogonadism). Testicular failure: Though less common than pituitary failure, testicular failure may also be responsible for low T. It's caused by diseases or illnesses affecting the testicles, injury or trauma to the testicles, or certain medicines and treatments such as chemotherapy or opioid pain medication. Providing your complete medical history to your doctor is always the first step toward a proper diagnosis.  What are the symptoms of low T?  The following indicators could be a sign that you have low T, say the doctors.  Lack of motivation and determination, including mild depression  Loss of physical endurance and muscle strength  Loss of or diminished early morning erections  Reduced libido (sex drive)   Erectile dysfunction (ED — difficulty achieving or maintaining an erection)   Gynecomastia (male breasts)  Small testes  T and Time: T levels in men naturally begin to decline by about 1% a year starting at age 30.  How do you test for low T?  "There are different methods for testing testosterone levels," says Dr. Kuhadiya. "Each approach uses a blood sample to evaluate total testosterone, which includes free and attached testosterone that combines with proteins albumin and sex hormone-binding globulin (SHBG). For the most accurate results, testing is based on samples collected in the morning after fasting, and from tests on two different days."  What treatment options are available?  "Well, your best natural option may be YOU," says Dr. Kahlon. "Men with pituitary failure are often able to treat their low T by losing weight to increase levels of the hormone. And even if you don't lose weight, exercise can help boost your testosterone. Unfortunately, if you have testicular failure, weight loss and exercise may not have the same effect."  So, are there other options? "You may want to consider Testosterone Replacement Therapy (TRT)," says Dr. Kuhadiya. "TRT is only available to men who are hypogonadal — with a clinical diagnosis of low T. Injection, gel, skin patch and nasal spray are available TRT options. The best option is the one that works best for the patient. Convenience, insurance coverage and cost are all factors to consider." Dr. Kahlon's TRT preference? Daily gel treatments, which are applied directly to the skin. On the other hand, Dr. Kuhadiya recommends intramuscular injections, which take place once a week or every two weeks.  But both doctors agree on this: physicians and their patients need to weigh the benefits and risks of TRT before proceeding with treatment — especially if your low T condition may require lifelong treatment. "In my clinical practice, I have seen some very good long-term results with an improved quality of life," says Dr. Kuhadiya. "However, in certain situations, TRT may increase the risk of heart disease and is not recommended for men with a history of prostate cancer." Dr. Kahlon adds, "Patients receiving any type of hormone therapy need to be closely monitored throughout the treatment process for any changes in their health."   How do you feel about steroids and T boosters?  "I don't recommend them, certainly not for hypogonadism," advises Dr. Kahlon. "There is no evidence to support anabolic-androgenic steroids or testosterone boosters as a safe or effective treatment for low T in men."  "In fact, there continues to be emerging evidence they may lead to side effects that could potentially harm the liver and the pituitary and endocrine functions of the body," warns Dr. Kuhadiya. "And that damage may be irreversible."
