Adjuvant Chemotherapy Considerations for Stage 1 Rectal Cancer
Recently, my mother, aged 54, received a diagnosis of Stage 1 rectal cancer and has already undergone a LAR procedure five weeks ago. Fortunately, it was not necessary for her to have an ileostomy, and she is currently on the mend at home. The initial biopsy taken during a colonoscopy revealed Intramucosal carcinoma with features indicative of Signet Ring Cell. Following her surgery, the final pathology report classified her cancer as Stage 1 (T1N0), specifically a moderately differentiated mucinous adenocarcinoma. Notably, there were no signs of lymphovascular invasion or perineural invasion, no tumor deposits, and no perforation. Additionally, her tumor displayed a low budding score, and all 13 lymph nodes examined were clear. MMR IHC testing confirmed that the tumor is microsatellite stable (pMMR). Her oncologist has advised a treatment plan involving six months of oral Capecitabine, primarily due to the presence of the signet ring cell characteristic in the initial biopsy. We are aware that the NCCN guidelines typically do not endorse adjuvant chemotherapy for Stage 1 cancers, yet her physician is cautious, citing the SRC findings as a potential risk factor. I would greatly appreciate insights regarding my mother’s treatment strategy. Are there others in this community who have received adjuvant chemotherapy even when classified as Stage 1 or low-risk Stage 2, contrary to what is typically advocated by NCCN guidelines?

Summary: Your mother has been diagnosed with Stage 1 rectal cancer and has undergone surgery. Although she is low risk according to typical guidelines, her oncologist recommends adjuvant chemotherapy due to specific tumor characteristics. This approach, while atypical, aims to minimize recurrence risk.
Explanation: Stage 1 rectal cancer typically does not require adjuvant chemotherapy, especially when there are no adverse features like lymphovascular invasion or significant tumor deposits. However, the presence of the signet ring cell type, which can be more aggressive, may justify additional treatment as a precaution. The goal of chemotherapy in this scenario is to further reduce the likelihood of recurrence despite her overall favorable prognosis.
Next Steps:
-
Discuss Concerns with the Oncologist: Have an open dialogue with her oncologist about the rationale for recommending Capecitabine. It's important to understand their reasoning and how they weigh the potential benefits against the risks involved in chemotherapy.
-
Consider a Second Opinion: If you are uncertain about the treatment plan, obtaining a second opinion from another oncologist specializing in gastrointestinal cancers could provide additional insights and reassure you about the recommended approach.
-
Learn About the Treatment: Research Capecitabine, its common side effects, and how it might impact her recovery. Understanding what to expect can help in managing her comfort during treatment.
-
Support and Monitor: Be there to support her physically and emotionally. Help her follow any lifestyle adjustments (like a balanced diet and regular, gentle physical activity, as tolerated) that can aid in her recovery.
-
Stay Informed: Keep track of her health, any changes in symptoms, and side effects during treatment, should she proceed with the chemotherapy. This monitoring can be beneficial for her healthcare team to adjust her treatment as needed.
If you have any specific concerns or need more information about what to expect during her treatment, feel free to ask.

Unexplained Lump on the Penis
At 22 years old and in good health, I maintain an active lifestyle without any medications or smoking habits. Recently, I've noticed a small, pimple-like lump on the shaft of my penis. This bump does not cause any itching, pain, or discomfort, nor does it seem to burst when pressure is applied. I have been inactive sexually for several months now. What could this condition be?
Concerns About My One-Year-Old's Response to Her Name
I have a daughter who just turned one year old. She measures 29 inches in height and weighs 20 pounds, and she has no significant medical history and isn't on any medications. Lately, she has been quite vocal, engaging in babbling and stringing together around two to four words. Additionally, she is very expressive—smiling often and maintaining a good amount of eye contact. She's also quite active; she crawls, cruises along furniture, and can stand for brief moments. However, I'm noticing that she doesn’t consistently react when I call her name. Occasionally, she does respond if I call her from another room, but she doesn’t seem to follow commands on a regular basis. Is this something I should be concerned about?
Navigating the High Costs of Colonoscopies
Hello everyone, I'm a 23-year-old female and I've just learned that my upcoming colonoscopy this Thursday is going to set me back over $2,000 out of my own pocket, despite having insurance. I genuinely didn't anticipate such a hefty expense. I can't help but feel a bit cheated! I’ve been told I have decent health insurance, so I’m puzzled about why this routine 30-minute procedure comes with such a high price tag, especially when pathology fees are additional on top of that. It’s honestly a little daunting, and I find myself hoping that there aren’t any serious health issues, simply because affording treatment could be a struggle. I’m curious to know, what have others paid for their procedures?
Concerns About My Child's Health
As a newcomer to Reddit, I'm reaching out in hopes of finding some much-needed guidance regarding my child's health issues. My little one, who is 2 and a half years old, has experienced swollen lymph nodes on the right side of his neck for the past three weeks without any accompanying illness. It's concerning to see them protruding visibly. Although healthcare professionals express a lack of concern since he appears healthy, I'm struggling to understand how this can be the case when swollen lymph nodes usually indicate an infection. Recently, these nodes have increased in size and are starting to cause him discomfort, leading him to scratch at his neck. Additionally, his feet tend to turn a deep purple color whenever he walks or stands, and it takes around 15 to 20 seconds for them to regain their usual hue after applying pressure. I've been told by the doctors that these two symptoms aren't related, but I can't help but think they might be connected given the circumstances. I've taken him to see two different doctors, but I still have no answers. Their guidance has simply been to monitor the situation and to reach out again if his condition worsens. I am extremely worried that this might indicate something serious, and it’s frustrating that the doctors seem unsure about what could be causing these symptoms. Any advice or insights would be greatly appreciated, particularly from those who might have dealt with similar issues in their children. It would be helpful to have something concrete to discuss with the doctors at our next visit.
Exploring Left Side Discomfort: Lower Back and Thigh Pain Concerns
For the past couple of weeks, I've greatly increased my physical activity—walking significantly more than usual (about three times my regular amount, according to my fitness tracker) and cycling, an activity I had not engaged in for over a year. I also had a couple of minor falls, neither of which seemed severe. During my flight home, I began to notice pain in my lower back, particularly concentrated in an area just above my right buttock. While showering on Tuesday, I discovered tenderness in a region between my thigh and groin while scrubbing; my index finger had been touching this sensitive spot. It’s situated quite deep and obscured by surrounding tissues, and has a bony feel reminiscent of the ligaments in my wrist. Tracing this tenderness back, it appears to extend toward my perineum—located between the anus and the testicles. I’ve examined my genitals thoroughly and found no discomfort in the penis, testicles, or the attached cords. However, this sensation feels distinctly like a ligament far deeper within the tissue, toward the outer thigh area, and it’s no longer painful to touch. Interestingly, I can't feel the same structure on my right side, which might just be due to unfamiliarity. This issue has predominately affected my left side. Coupled with this, I've noticed sporadic numbness in my outer right thigh when lying down; this has been a recurring experience throughout much of my adult life. However, just yesterday, I experienced excruciating pain (described as a 10 out of 10) at certain angles, which was distressing enough to alarm my family. While moving around allows me to reduce the pain to about a five, it sometimes lingers, taking a while to fully dissipate. The discomfort seems to be localized in the space between the two fingers I referenced earlier. Could this be a systemic issue? Is there a possibility that a pinched nerve is impacting both sides of my body simultaneously, or could this be a combination of various issues? While I recognize that a definitive diagnosis can't be given in this setting, I would appreciate guidance on whether these symptoms should prompt an urgent medical visit or if they can be monitored for a while. Details about me: I’m a 37-year-old male, white, weighing 200 pounds, standing six feet tall, and I lead an active lifestyle while taking 15 mg of Lexapro daily.
