Colorectal cancer incidence rates in adults over 55 have been dropping for several decades, thanks in part to greater use of screening for the illness, particularly colonoscopy, which can detect and remove polyps before they become malignant.
When studies simply take into account body weight at the time of diagnosis, the true link between obesity and the risk of colorectal cancer is obscured. The new study also demonstrates that inadvertent weight reduction may serve as a precursor to colorectal cancer. A wide variety of malignancies are at risk because of obesity. This connection is notably evident, for instance, in the cases of colorectal, kidney, and endometrial cancer. Previous estimates indicate that the risk of colon cancer in obese people is around one-third higher than in normal weight people.
The new tool accurately predicts how aggressive a colorectal tumor is, how likely the patient is to survive with and without disease recurrence, and what the optimal therapy might be for them.
Colorectal cancer is one of the common cancers in the body. Overall, it's the third most common cancer of the body and each one of us has around 4-5 per cent lifetime risk of developing colorectal cancer. Moreover, initially it was thought that maybe it's a white man's disease.
According to experts, while it is common to think that having a family history makes it difficult for one to keep cancer at bay, the disease is quite often lifestyle driven and even in hereditary cases, prevention and early diagnosis can improve outcomes.
Colorectal cancer presents several symptoms and risk factors which can help in identifying it early. The symptoms of Colorectal cancer vary from patient to patient in terms of size, and location in the large intestine. Several people with colon cancer do not experience any symptoms in the early stages of the disease.
One of the most common areas colorectal cancer spreads to is the lungs, affecting up to 18 per cent of patients with colorectal cancer.4 Detecting cancerous nodules in the lung early provides patients with the best outcomes, but there are no evidence-based standards for when and how often to screen colorectal cancer patients with chest CT or PET scans.
A new study published in the New England Journal of Medicine (NEJM) has claimed that colonoscopy does little or no better than symptomatic examination when it comes to picking up colorectal cancer early.
These smart nanoparticles are stable under physiological conditions and degrade at tumour sites in the presence of redox stimuli of cancer cells.
The module uses advanced AI software to highlight suspicious polyps of various sizes, shapes, and morphologies with a visual marker in real-time. It serves as the gastroenterologists’ ever-vigilant second observer, with a sensitivity rate per lesion of 99.7 per cent and less than 1 per cent false positives.
Colorectal cancer is the fifth most commonly diagnosed cancer in India and accounts for five percent of all cancer cases. It is very difficult to pinpoint the exact cause of the rise in colorectal cancer. The reason is multifactorial like sedentary lifestyle, obesity, smoking, alcohol use, low-fibre, high-fat diets and diets high in processed meats.
