Inquiries About Smoking and Lung Cancer Risks
Hello, physicians, I wanted to share a bit about my background: I am a 27-year-old male who smoked for a total of five years, specifically from 2020 to 2022 and then again from 2024 to 2025. I quit yesterday. Back in April 2025, I had a consultation with a pulmonologist where I underwent a pulmonary function test (PFT) and an X-ray. Both results came back normal, as confirmed by the doctor, though I unfortunately cannot provide the report here. I have a few questions: 1. Based on my smoking history of approximately 3 to 5 cigarettes per day for five years, am I at risk of developing lung cancer? 2. Is it necessary for me to get a low-dose CT scan for cancer screening? 3. Since I quit smoking shortly after my visit to the pulmonologist, should I consider repeating the pulmonary function test? I tend to have a bit of obsessive-compulsive behavior, which is why I’m reaching out with these concerns.

It's great to see that you've decided to quit smoking; that's a significant step toward improving your health. Let’s address your concerns regarding your smoking history and lung cancer risks.
-
Lung Cancer Risk: Smoking is indeed a primary risk factor for lung cancer, but your risk depends on various factors, including how much and how long you smoked. While smoking 3 to 5 cigarettes per day for five years does increase your risk compared to non-smokers, it's notably lower than someone who has smoked heavily or for a longer duration. Your recent normal pulmonary function test (PFT) and chest X-ray are reassuring signs that your lungs are currently functioning well.
-
Low-Dose CT Scan for Screening: Current guidelines typically recommend low-dose CT screening for lung cancer primarily for adults aged 50–80 who have a significant smoking history (e.g., 20 pack-years). Given your smoking history (which equates to about 1.5 pack-years), routine screening isn’t necessary at this point. However, it’s essential to stay vigilant about any new symptoms such as persistent cough, unexplained weight loss, or chest pain.
-
Repeating the Pulmonary Function Test: Since your PFT results were normal and you recently quit smoking, a follow-up may not be immediately necessary unless you experience new respiratory symptoms. Many people notice improvements in lung function after quitting smoking, so it might be beneficial to monitor how you feel over the next several months before considering a repeat test.
Next Steps:
- Monitoring: Keep track of any changes in your health, especially respiratory symptoms, over time. If any concerning symptoms arise, consider checking in with a healthcare professional.
- Stay Smoke-Free: Continue with your commitment to remain smoke-free. This decision greatly reduces your risk of lung cancer and improves overall health.
- Healthy Lifestyle: Focus on maintaining a healthy lifestyle, including a balanced diet, regular exercise, and hydration. These can support lung health and overall well-being.
Your proactive approach to your health, including reaching out with these concerns, is commendable. If you have further questions or want to discuss your situation in more detail, feel free to ask.

Strange Jelly-Like Substance Observed from Wound
I’m a 21-year-old female living with an auto-inflammatory condition known as hidradenitis suppurativa (HS). Recently, I've experienced a concerning issue with one of my wounds. This particular wound causes significant pain and excessive bleeding. However, whenever I attend to it, I tend to find this unusual jelly-like substance present within it. Interestingly, this phenomenon has only occurred with this one wound and not any of the others I have. The bleeding seems to persist until I manage to remove this jelly substance, after which it typically slows down and comes to a halt completely. I’m seeking insights into what this might signify so that I can effectively discuss it with my healthcare provider.
Understanding Tuberculosis Exposure Risk
A 26-year-old male, who neither drinks alcohol nor smokes, seeks to understand the implications of exposure to tuberculosis (TB). As an anesthesia technician, I became concerned after I encountered a TB-positive patient about a month ago. I had to enter the patient’s room several times to perform blood gas tests. On my first entry, I mistakenly wore my N95 mask incorrectly due to the hectic nature of attending to multiple rooms. From my research, it appears that TB is quite transmissible; direct exposure can pose a serious risk of infection. Transmission usually requires prolonged contact with an infected individual, particularly in a close or face-to-face setting. In this case, the patient was lying face down and appeared to be sleeping when I entered. I have already undergone testing for TB, but I am eager to deepen my understanding of the risks involved in these situations.
24M | Unexplained Fainting Incident
**Note:** I previously shared this story, but it was inexplicably removed. I’m a 24-year-old male without any medical diagnosis or prescription medications. While I do consume alcohol occasionally, I hadn’t been drinking before this happened. Around 3 a.m., I got up from bed to use the restroom. As soon as I began to urinate, I suddenly felt a wave of dizziness. The next moment I was aware of was regaining consciousness in the bathtub, startled awake by the sensation of something dripping on me—only to discover it was my own blood. This was my first experience with fainting. When I came to, confusion set in. I was disoriented and couldn’t comprehend why I was being dripped on while in what I thought was my “bed.” Strangely, I also imagined that I was lying on a collection of marbles (which I actually don’t own)—this turned out to be the shattered glass of my shower door lying around me. I’m uncertain whether I lost consciousness first and then fell, or if the fall caused my brief blackout. It took me a few moments to understand why I was in the bathroom at all. I’m not sure how long I was out; I only remember it was around 3 in the morning when I initially got up, and about the same time when I regained consciousness. I dialed 911, and the ambulance arrived promptly. They checked my vitals, performed an EKG and measured my blood sugar, finding nothing unusual. At the emergency room, they repeated the vital checks, conducted a CT scan, drew blood, and took x-rays—yet still no abnormalities were detected. I had several cuts on my face and left arm (curiously, this is the arm that would have been turned away from the door), along with bruising around my ribs. Since the incident, I’ve been suffering from headaches and pain in my ribs. I received stitches on both my face and arm. The nurse suggested I could have stronger pain relief, but I opted for just Toradol. They eventually discharged me, stating, "We’re unsure what caused this, but return if it happens again." What might have triggered such an incident? How can I safeguard against it reoccurring if they remain uncertain about the cause?
Healing Progress Post-GBS: Toe Concerns
I am a 28-year-old male, measuring 5 feet 10 inches and weighing 131 pounds. My current medications include Fomadatine and Zyrtec, prescribed due to my ongoing battle with Chronic Gastritis and SIBO. I maintain a healthy lifestyle, abstaining from both smoking and alcohol. My health concern revolves around the toe adjacent to my pinky toe on my left foot, as well as my pinky toe on the right foot. Since August of last year, I have been on the mend from Guillain Barre Syndrome. Recently, I've noticed that at night, the skin on my feet tends to turn a reddish pink, although this usually improves after I walk around. However, two of my toes have remained red, with one appearing slightly swollen. Generally, my pinky toes are quite thick, but the condition of my left foot's toe is worrisome for me. It seems that I'm unable to upload an image to illustrate my issue.
Swelling Beneath My Chin Near the Jawline
18-Year-Old Male: I'm reaching out to any medical professionals who might provide insights into my situation. I've been using marijuana since I was 14, but now, at 17, I'm making an effort to stop and have been clean for 18 days. Recently, I've discovered an unusual swelling located just beneath my chin, behind my jaw. It causes some discomfort when I move, yet it doesn’t feel painful continuously. I'm somewhat anxious that this could be indicative of a more serious issue, especially considering it's positioned near my chin's lymph nodes. Any advice or information would be greatly appreciated as it might help alleviate my worry.
