Should I Undergo a Low-Dose CT Scan for Cancer Screening?
Hello, Doctor. I’d like to share some details regarding my health history: I am a 27-year-old male who has a past of smoking cigarettes. My habit began at about three cigarettes a day from 2020 until 2022. Following a one-year cessation, I resumed smoking approximately five cigarettes daily from August 2024 until June 2025, but I have since quit recently. I do not have any issues with high blood pressure or diabetes. In April, I had an appointment with a pulmonologist who conducted pulmonary function tests and a chest X-ray, both of which returned normal results. Consequently, I have made the decision to quit smoking entirely, as I successfully reduced my cigarette intake from five to just two. Given my gradual withdrawal from smoking, do you think it is necessary for me to have a low-dose CT scan for cancer screening? Thank you for considering my concerns. Best regards.

It’s great to hear that you’ve made significant progress in quitting smoking, and I commend you on your commitment to your health. Regarding your question about undergoing a low-dose CT scan for cancer screening, here are the main points to consider:
-
Current Guidelines: Most health organizations, including the U.S. Preventive Services Task Force (USPSTF), recommend low-dose CT scans for lung cancer screening primarily for adults aged 50 to 80 who have a history of heavy smoking (defined as a 20 pack-year history) and who still smoke or have quit within the past 15 years.
-
Your Smoking History: You mentioned you smoked two cigarettes a day for a few years, which does not meet the criteria for “heavy smoking.” Your recent quitting is fantastic, but based on the current guidelines, you might not be a candidate for routine low-dose CT lung cancer screening at this time.
-
Normal Pulmonary Function Tests and Chest X-ray: The fact that your pulmonary function tests and chest X-ray returned normal results is reassuring. These results typically indicate that you do not currently have lung issues that would necessitate further screening.
Next Steps:
-
Continue to Avoid Smoking: Stay committed to your smoke-free lifestyle. This greatly reduces your risk of developing lung cancer and other smoking-related diseases.
-
Routine Health Check-ups: Keep having regular check-ups with your healthcare provider to monitor your overall health, especially lung function, given your past smoking history.
-
Monitor Symptoms: Be aware of any new symptoms such as cough, unexplained weight loss, or persistent chest pain. If you notice any changes, discuss these with your healthcare provider.
-
Healthy Lifestyle Choices: Maintain a balanced diet, regular exercise, and minimize exposure to environmental toxins—all of which are beneficial for lung health.
If your situation changes or if you have any additional concerns in the future, don’t hesitate to reach out for a personalized assessment. Your proactive approach to health is commendable, and maintaining a focus on general wellness will serve you well.

Concerns About Telemedicine during a Drive
Hello everyone, I'm a 28-year-old woman with a background of thyroid cancer, necessitating routine check-ups every six months. Recently, a question came to my mind regarding the professional conduct of my primary care physician. I was taken aback to learn that she participated in my telemedicine appointment while driving. I've noticed her appearing somewhat distracted during our in-person visits and at times, she forgets the medications we discuss during our reviews, but this situation felt even more inappropriate. It’s challenging for me to comprehend why I’m spending $450 post-insurance for what feels like a casual video call when it’s clear she is multitasking. Although I've been under her care for about two years, I'm eager to find a practitioner who will genuinely take the time to understand my health history and build a long-term relationship. I appreciate any insights you can offer!
Concerns About a Recent Lump on My Shaft: Seeking Guidance
I’m a 20-year-old male with allergies primarily to wood, pollen, and grass, which used to cause me hives, but that issue has resolved. Now, to address the main concern. I found a lump on my shaft while showering yesterday morning, and it caught me off guard. Up until now, I haven’t experienced any discomfort, and I still feel largely fine. The size of the lump is similar to that of a pimple or possibly a cyst, but I'm unsure. I'm contemplating whether it would be wise to consult a doctor about this issue, as I want to be informed on how to proceed. Any advice would be greatly appreciated!
Should We Handle This Ear Issue at Home or Seek Medical Attention?
I’m sharing this on behalf of my husband, a 33-year-old male who is not currently taking any medications and has no known chronic conditions. The only relevant detail is that he has a significant issue with earwax accumulation. At times, this leads to noticeable deposits on his pillow when he sleeps on his side, affecting his hearing. For the past few days, his ear has exhibited symptoms similar to what is often seen in various ear conditions. He reports feeling a sense of discomfort, although there is no pain or itchiness involved. Touching or tugging on the tragus and surrounding areas does not elicit any pain. He’s uncertain why there are scabs around this area. He mentioned experiencing a sensation of fluid inside the ear yesterday, prompting him to use some over-the-counter peroxide drops to help clear it out. He described the output as a thick, opaque discharge resembling earwax, but darker and more liquid in texture. Today, while the fullness sensation seems to have diminished, the discomfort remains. His other ear appears normal, perhaps just slightly dry, but nothing more than what is typical for ears. Given this information, I'd like to know whether this is a situation he can manage at home or one that warrants a visit to urgent care. Additionally, what might be the underlying issue?
Distinguishing Between Norovirus and Influenza: Seeking Insights
I know I recently shared an update, but I realized I overlooked an important question. My 28-year-old husband has been feeling unwell since early this morning, although he seems to be on the mend. He experienced a single episode of vomiting and has had diarrhea 3-4 times today. Since he started expressing discomfort, we have been entirely apart to prevent any possible spread of illness. Given his symptoms, could this be Norovirus or Influenza? Currently, he is suffering from a headache, feels unusually warm (though we don’t have a thermometer, so I can’t confirm if he has a fever), and is experiencing soreness in his legs. Additionally, his throat was quite painful for much of the day, particularly after vomiting, which might be due to a globus sensation. He has taken a total of 12mg of ondansetron, administered in intervals of six hours. For reference, he weighs 230 pounds, seldom consumes alcohol, has Puerto Rican heritage, is a former smoker, and does not use any illicit substances.
