Blood and Mucus in Stool: Are Skin Bumps a Sign of Cancer?

Blood and mucus in the stool, along with the presence of pimple-like lesions on the face and body?

Hello doctor, I am 51 years old.
Two days ago, I noticed mucus and blood when wiping after a bowel movement.
Additionally, I have developed what looks like pimples on my body and face.
These similar lesions have appeared since I returned from Penghu in early August, disappearing for two to three days before reappearing.
Initially, I consulted a dermatologist who said it was an allergy.
Also, my older brother has colon cancer.
Given these symptoms, is there a possibility that I might have cancer?

Your stool has mucus and blood streaks, and since your older brother has colon cancer, it is recommended that you consult a gastroenterologist for further evaluation, such as a colonography or colonoscopy, to determine if there is any presence of colon cancer.
As for the acne-like lesions on your face, they are likely related to a dermatological issue and are not associated with colon cancer.

When it comes to symptoms such as blood and mucus in the stool, along with the appearance of skin bumps, it is essential to approach the situation with caution and seek medical advice. The presence of blood and mucus in the stool can be indicative of several gastrointestinal issues, ranging from benign conditions to more serious concerns, including colorectal cancer, especially given your family history of colon cancer.
Colorectal cancer can present with symptoms such as changes in bowel habits, blood in the stool, abdominal discomfort, and unexplained weight loss. The fact that you have noticed blood and mucus during bowel movements warrants a thorough evaluation by a healthcare professional. It is crucial to undergo a colonoscopy, which is the gold standard for diagnosing colorectal issues, including cancer. This procedure allows for direct visualization of the colon and rectum and the opportunity to take biopsies of any suspicious lesions.

Regarding the skin bumps you mentioned, while they may have been initially diagnosed as an allergic reaction by a dermatologist, it is important to monitor any changes in these lesions. Skin changes can sometimes be associated with systemic conditions or malignancies, including skin cancer. If these bumps are persistent, changing in appearance, or accompanied by other symptoms, a follow-up with a dermatologist or an oncologist may be necessary.
Your family history of colorectal cancer is a significant risk factor. Individuals with a first-degree relative who has had colorectal cancer are at an increased risk themselves. It is advisable to discuss with your healthcare provider about the appropriate screening protocols, which may include earlier and more frequent colonoscopies.

In summary, while the symptoms you are experiencing could be related to benign conditions, the combination of blood and mucus in your stool and the presence of skin bumps, especially in the context of a family history of cancer, necessitates further investigation. Do not hesitate to reach out to your healthcare provider for a comprehensive evaluation and to discuss your concerns. Early detection and intervention are key in managing potential health issues effectively.
