Patient Reviews

It was an excellent experience seeing Dr' Klass.Everything was explained clearly and frankly and I appreciated it very much. I'm glad to have my care in her hands.

June 15, 2025

5

Loved the doctor! There needs to be more time allotted for each patient as she spends extra time with each patient. Scheduling larger time slots could serve to be helpful.

June 13, 2025

5

Dr Klass is exceptional - kind , caring, encouraging and knowledgeable about the treatment plan for my case. I feel very fortunate to have her managing my care .

June 9, 2025

Dr Klass was fantastic. She answered all of our questions and explained my condition wonderfully. She put us at ease after a lot of anxiety. She gave us a plan for future treatments. She was wonderful and very knowledgeable. Also a special thanks to Dr. Sig Rosenbloom .

June 8, 2025

5

Dr.Klass is very thorough. She makes sure she answers all my questions and makes sure I understand before I leave. She is very personable and never rushes out like a lot of doctors. I always feel like I am being heard and not a number! Her staff is great as well.

June 7, 2025

5

I love Dr Klass. She is not only very knowledgeable but she is very empathetic. She'll listens and explains with details in a way simple to understand. I'm blessed to have her as my doctor.

June 7, 2025

I've never met a kinder, more caring group of ladies in my life! They truly are outstanding, and if it's possible to love an oncologist, I love mine! There's a level of trust with this practice and Dr. Klass that I haven't experienced with any care provider I've ever had - my hats off to them! My frustrations come with the extreme amount of over communication with the check in/out process, one notification would be appreciated, not 17! Billing is also another one, here's your estimate, no that's not right, here's your new bill, nope that's not right - oh billing it a month behind so disregard it. I work full time, I do not need all this congestion clogging my emails and text messages!

May 15, 2025

The only down side to seeing Dr. Klass is that she's so thorough and takes the time needed with each patient rather than time scheduled. That meant my I saw her at 2:15 instead of the scheduled 12:45 appointment. She's probably the only doctor I would wait that long for.

had 10:15 am appointment, didn't get seen until 12:15 pm, not good

May 11, 2025

The only down side to seeing Dr. Klass is that she's so thorough and takes the time needed with each patient rather than time scheduled. That meant my I saw her at 2:15 instead of the scheduled 12:45 appointment. She's probably the only doctor I would wait that long for.

I've never met a kinder, more caring group of ladies in my life! They truly are outstanding, and if it's possible to love an oncologist, I love mine! There's a level of trust with this practice and Dr. Klass that I haven't experienced with any care provider I've ever had - my hats off to them! My frustrations come with the extreme amount of over communication with the check in/out process, one notification would be appreciated, not 17! Billing is also another one, here's your estimate, no that's not right, here's your new bill, nope that's not right - oh billing it a month behind so disregard it. I work full time, I do not need all this congestion clogging my emails and text messages!

Dr.Klass is very thorough. She makes sure she answers all my questions and makes sure I understand before I leave. She is very personable and never rushes out like a lot of doctors. I always feel like I am being heard and not a number! Her staff is great as well.

Loved the doctor! There needs to be more time allotted for each patient as she spends extra time with each patient. Scheduling larger time slots could serve to be helpful.

Make Colon Health Your Habit

For many people, talking about colon health can be a little uncomfortable. However, medical issues don’t just go away if you ignore them.

Being proactive about your well-being with preventative care can help catch colorectal cancer or another serious condition early, often before it becomes a bigger problem.

Wellstar is committed to keeping your colon healthy with preventative screenings and expert care, so you can continue to live well.

Catch colon cancer early

Early detection is the best prevention, especially when it comes to colon cancer. If caught early, colorectal cancer has a survival rate of 91%.

“Colon cancer is the second most common cause of cancer death in the United States, so it’s very important that everyone gets screened,” said Wellstar Gastroenterologist Dr. Cameron Body. “For an average risk person, screenings should begin at age 45.”

Those with a higher risk or a family history of colorectal cancer may need to start screening sooner. Partner with your provider to create a personalized screening plan—and stick with it to stay ahead of the disease.

“Recently, colon cancer has been a major trending topic in public discourse, and it has been impacting younger individuals each year. It is important to start colon cancer screening at the age of 45 or sooner if you have a family history of colon cancer,” said Wellstar Gastroenterologist Dr. Nikhil Kadle. “This is a preventable disease, so please speak with your primary care provider or gastroenterologist to help get you screened. Colonoscopies can help prevent colon cancer, diagnose and help direct early treatment if you are diagnosed.”

The death rate for colon cancer in older adults has been decreasing for the past several decades due to screenings, according to the American Cancer Society. Screenings can identify polyps before they become cancerous and can catch cancer earlier when it is more easily treatable. However, in people under 55, death rates from colon cancer have been increasing by about 1% per year since the mid-2000s.

Why colonoscopies work

During a colonoscopy, a Wellstar gastroenterologist will view the inside of your colon and look for polyps or any other abnormal tissue that could be cancerous. This preventative testing is key to catching colorectal issues at the start.

“A colonoscopy is the gold standard when screening for colon cancer. The procedure itself is not painful, and we make sure you’re comfortable throughout the process,” Dr. Body said. “The goal is to do a high-quality exam with a good prep to find polyps when they’re small and get them removed to minimize the risk of them subsequently developing into cancer.”

Polyps take about five to 15 years to evolve into an invasive cancer, according to Dr. Carmen Klass, oncologist and hematologist with Northwest Georgia Oncology Centers, a care partner of Wellstar.

“If you have a colonoscopy every five to 10 years, they can remove the polyp and it will never be declared an invasive cancer,” Dr. Klass said. “In fact, if all Americans did their screening colonoscopies every five to 10 years, the death rate for colorectal cancer would drop by 50%.”

Signs of colorectal cancer

  • Colon cancer is typically discovered when a patient has a colonoscopy, but it’s important to watch for these warning signs:
  • A change in your bowel habits, such as persistent diarrhea or constipation
  • Bloody stools or rectal bleeding
  • Abdominal discomfort, such as cramps, gas and pain
  • Feeling like you are unable to empty your bowels completely
  • Weakness or fatigue
  • Unexplained weight loss

If you experience any of these symptoms, contact your care team right away.

Colorectal cancer care at Wellstar

If you have been diagnosed with colorectal cancer, count on Wellstar for comprehensive, personalized care. Our specialists will work together with you to form a tailored treatment plan and offer support every step of the way.

“When a patient is diagnosed with cancer, we walk with them and guide them on this difficult journey,” Dr. Klass said, sharing how Wellstar provides compassionate care.

Wellstar offers medical expertise close to home, clinical trials and state-of-the-art surgical procedures to treat colorectal cancer. We also have a multidisciplinary gastrointestinal (GI) tumor board that diagnoses and creates treatment plans collaboratively.

Along with cancer surgeons, medical oncologists and other experts, our care team also includes nurse navigators, dietitians, social workers, psychologists, psychiatrists and counselors to provide complete care and support.

Get answers with genetic testing

Whether you have been diagnosed with colorectal cancer or are concerned about the chance of developing it, genetic testing can help you understand your risk of getting the disease.

If your parent, sibling or child has had colorectal cancer, you are two to three times more likely to develop the condition compared with someone with no family history. Our genetic counselors can help determine how genetic testing could benefit you and your family.

“Wellstar offers support from genetic counselors to help keep other family members safe in the future,” Dr. Klass said.
