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.

Understanding Abnormal Blood Tests: What Do These Results Indicate?
Hello Doctors, I appreciate your assistance in reviewing my situation! I’m a 34-year-old female with a history of hypothyroidism, and aside from that, I have generally been in good health. Recently, I have been experiencing some troubling symptoms including recurring canker sores, severe fatigue, occasional muscle weakness, and shortness of breath. These issues prompted my visit to a physician who then referred me to a rheumatologist after noting some low positive results for ANA and a positive finding for Anticardiolipin antibodies. During my appointment, the rheumatologist observed considerable inflammation in my joints and subsequently diagnosed me with inflammatory arthritis. This diagnosis is puzzling to me, as I do not experience any joint pain or stiffness, which makes me question its accuracy. In the follow-up blood tests, results showed a negative for both Anticardiolipin antibodies and ANA. However, several other markers were abnormal: - Low Mean Platelet Volume (MPV): 6.9 - Elevated Chloride: 109 - Low Carbon Dioxide (CO2): 20 I am curious if these abnormal values could hold any significance given my current health status. Thank you once again for your help!
Should I Consider Visiting the Emergency Room?
Age: 18, Height: 5'5", Weight: 170 lbs (I’ve lost quite a bit of weight recently due to decreased appetite). While I don't feel like I'm in immediate danger, my lack of health insurance makes me hesitant to seek medical attention. Would it be sensible to incur an emergency room bill? My family also lacks health insurance, which amplifies my anxiety. My father believes that my various health issues stem from my weight, and to a degree, that's accurate. I have been unhealthy for some time, but I'm actively trying to improve. Let me trace back the issues that have arisen over the past several weeks. About two or three weeks ago, I began experiencing significant pain in my pelvic and abdominal regions, accompanied by an urge to urinate every quarter of an hour. At first, I was able to hold it for around 45 minutes, but delaying any longer resulted in discomfort. Initially, I suspected a urinary tract infection (UTI). However, since I cannot visit a doctor, my parents bought me cranberry juice in the hope of alleviating the symptoms. It soon dawned on me that I was merely dealing with frequent urination and lacked the other typical UTI symptoms. Given my weight concerns, poor dietary habits, and the health history of my family, I started to suspect that I might be dealing with diabetes, which caused a lot of anxiety. Random stabbing pain began occurring in my left foot, which happened infrequently at first but then became more persistent and severe. This pain had previously occurred in just my left foot, only to dissipate after a week or so. Since the onset of this pain, I've made a conscious effort to reduce my food intake and focus on healthier choices, suspecting diabetes. I initially thought it could be a pinched nerve since the discomfort mimicked what I had experienced before, but I soon reconsidered this theory as the pain started appearing in my right foot as well. Additionally, I've noticed a general aching in my legs, particularly my left one. Recently, a new ache has emerged in my lower back; I'm uncertain if it's connected or not. I'm feeling quite overwhelmed. This situation is distressing, and without a primary care physician to consult, I feel lost about what steps to take next.
Strange Cold Sensation in Feet Despite Warmth
Recently, I've been encountering an unusual cold feeling in my feet, almost like a combination of burning and numbness. Given that it's winter in my location, I initially assumed this was a result of my general sensitivity to the cold. However, when I check my feet, they feel perfectly warm, likely because I'm wearing socks. Yet, I can't shake off this persistent icy sensation. I'm not sure if I'm articulating my experience clearly. I'm perplexed by how this could happen. Is it possible that this feeling indicates a deeper issue, or am I just overanalyzing things? I’m a woman in my early twenties, without any known health issues, and I’m not taking any medications at the moment.

Understanding GBS and MCTD: A Patient's Journey
A 44-year-old woman, who stands 5 feet 8 inches tall and weighs 155 pounds, presents a medical history marked by supraventricular tachycardia (SVT). To summarize her experience, she received a flu shot at the end of November, after which she began experiencing a range of systemic symptoms. It started with an enlarged thyroid, severe headaches, and excruciating back pain. This was soon followed by widespread nerve pain and optic neuritis. After several weeks and a few orthopedic evaluations, she consulted with a neurology nurse practitioner (NP) who suspected a link to the vaccination, yet refrained from diagnosing it as Guillain-Barré Syndrome (GBS). An MRI of the brain was conducted to eliminate other potential conditions, yielding normal results with a follow-up planned for six months later. Determined to believe that her condition would improve, she found herself several months later with minimal progress and an array of dysautonomia symptoms, including ongoing SVT, blurred vision, fluctuations in blood pressure, and tinnitus. Although she experienced some reduced reflexes early on, she has not faced muscle weakness or coordination issues. Her new primary care physician (PCP) performed laboratory tests, which revealed positive results for antinuclear antibodies (ANA) and RNP antibodies, while other checks returned negative. Her NP is considering the possibility of mixed connective tissue disease (MCTD), but she remains convinced that her symptoms align more closely with a variant of GBS. Notably, she does not exhibit many of the usual symptoms associated with MCTD. With weeks, if not months, to wait for appointments with rheumatology or neurology, the uncertainty is becoming increasingly frustrating for her. She seeks insights from others on whether RNP antibodies are frequently found in cases of GBS, as her research suggests this occurs approximately 36% of the time. She is pondering whether her PCP should also check for GQ1b antibodies or perform an ANA test using fluorescence microscopy. As a knowledgeable nurse, she feels somewhat out of her depth in this situation, eager to address some of these questions while waiting for further medical guidance.
