Persistent Lump in Axillary Region
A 22-year-old female with no underlying health conditions or medications reports finding a lump beneath her arm close to her breast a few months ago, coinciding with the day before her menstrual cycle began. This lump is notably mobile; it moves under pressure like a grape in shape and size. On palpation, it feels distinctly round, with a texture akin to the tip of one's nose—not too firm but not squishy either. Despite its presence, there have been no changes in size, nor has it disappeared over time. The skin above the lump shows no abnormalities, and she has not experienced any related symptoms—her appetite, energy levels, and sleeping patterns remain unaffected. While the lump itself isn’t painful, prolonged touching can cause slight tenderness. There is also some swelling in the surrounding area during her menstrual cycle, leading to discomfort when lying on her right side. What could this indicate? The individual has researched swollen lymph nodes and cancer, leading to concerns about these possibilities. She is attempting to schedule an appointment with a gynecologist soon, all the while trying to manage her anxiety regarding the situation.

It's understandable to feel anxious about a persistent lump, especially when you've done some research and have concerns. Based on your description, the lump you're feeling is likely a benign (non-cancerous) condition, such as a cyst or a lipoma, particularly since it is mobile, tender only with pressure, and associated with your menstrual cycle.
Explanation:
- Mobile Lump: The fact that the lump moves under pressure suggests it's not attached to any underlying structures and is likely a benign entity.
- Menstrual Cycle Connection: Fluctuations in hormone levels during your menstrual cycle can cause changes in breast tissue, leading to lumps that can appear or feel more pronounced at certain times.
- Stable Size: A lump that hasn’t changed in size over several months is typically less concerning than one that grows rapidly.
Next Steps:
-
Symptom Monitoring: Keep track of any changes in the lump, such as size, shape, tenderness, or any new symptoms (like pain or skin changes). This can provide useful information for your healthcare provider.
-
Warm Compress: If tenderness occurs, try applying a warm compress to the area to ease discomfort.
-
Relaxation Techniques: To help manage your anxiety while you wait for your appointment, consider stress-reducing practices such as deep breathing, meditation, or gentle yoga.
-
Follow-Up Appointment: Continue with your plans to see a gynecologist. They can conduct an examination and may recommend an ultrasound if necessary, which is often a first step to evaluate breast lumps.
-
Educate Yourself If Needed: If you have lingering concerns, reading reputable information on breast health can sometimes help alleviate anxiety by providing a clearer understanding of what to expect.
It's great you're taking action by scheduling an appointment. Most lumps like the one you described are not cancerous, but it's always best to get a professional evaluation for peace of mind.

Concerns After Emergency Surgery: Seeking Guidance
Greetings! It has now been two weeks since I underwent an emergency laparotomy on July 3rd, where I had a large cyst and a portion of my right ovary removed due to ovarian torsion. Since the operation, I have been carefully cleaning the incision with water daily and making sure it dries thoroughly. Most of the swelling has subsided, and I have regained considerable mobility. However, I may have pushed myself a bit too much recently, as I've found myself sitting cross-legged and generally relaxing more, which is a positive sign of recovery. I completed my prescribed antibiotics on July 10th and finished the blood thinner injections in my abdomen by July 15th. For the past four days, I haven’t taken any pain relief, but I've started experiencing significant pain again in the last 24 hours. This discomfort manifests as a deep ache on the left side, where the knot of the dissolvable stitches is located, and it radiates down to the top of my right thigh. Currently, I find myself back in bed, needing to take codeine to alleviate the pain, as sitting up exacerbates the discomfort. I’ve noticed no redness around the incision, although there is still considerable bruising, and the area feels no warmer than the rest of my abdomen. Over the past few days, I’ve also been feeling slightly nauseous and unusually warm, which may be due to the hot weather. I’m concerned that there may be an issue with the dissolving of the sutures or perhaps the internal healing process in that specific area, which might explain the pain. Alternatively, could this just be a normal part of recovery? The surgeon did mention there would be both good and bad days. As this is my first experience with surgery, I’m uncertain about what is typical and would prefer not to seek a GP appointment unnecessarily if it turns out to be nothing serious. Any insights or advice on this matter would be greatly appreciated. Thank you!
Concerns Regarding Breast Discomfort
Demographics: Female, 23 years old, 5'4", weighing 120 pounds, with no prior health issues. The only notable breast cancer case in my family involves a great aunt, who experienced it twice. Additionally, there is a family history of breast cysts. For several years, my fiancée has reported experiencing pain in her breasts. In her teenage years, she underwent an ultrasound which yielded no concerning findings. However, since the start of this year, she's been feeling an increase in the frequency and intensity of the discomfort. The pain is primarily concentrated in one breast and intensifies around the time of her menstrual cycle. Symptoms include tenderness in multiple areas of the affected breast, a sense of swelling, some redness around the nipple, and a degree of nipple inversion, which she believes is a recent development. This is particularly troubling as these changes are confined to the problematic breast. We recently consulted a nurse practitioner in the OBGYN department who conducted a physical examination and did not detect any lumps. She noted some fibrous tissue in the unaffected breast but had no comments regarding the troubled one. Her evaluation did not suggest any urgent issues, and we are in the process of scheduling another ultrasound for further investigation. Given my family’s history with cancer, I've experienced significant anxiety surrounding this issue. Having lost numerous close relatives to the disease, the prospect of facing this situation again at just 27 is daunting. I'm deeply worried and am seeking potential explanations for her symptoms in an effort to alleviate my concerns as we proceed with our next steps.
Understanding the Side Effects of Ferrous Fumerate
A 28-year-old woman weighing 61 kg and standing at 5 feet 5 inches tall recently underwent a blood test which revealed that her iron and ferritin levels were only slightly above 8. For the past week, she has been taking one 210 mg ferrous fumerate tablet daily. However, three days ago, she began to notice some troubling symptoms, including skin itching, muscle discomfort, weakness, and cramps. Today, she developed an itchy rash that started with her ears and has since spread to her arms and chest. She is wondering if taking Piriton would help alleviate these symptoms and whether these reactions are typical side effects of the medication. She notes that there have not been any changes in her daily routine — including laundry detergent or body wash — that could account for these new symptoms. She intends to reach out to her GP for further guidance tomorrow.
Duration for Keeping Surgical Dressing On
I am 35 years old and reside in the UK. Last Friday, I underwent a thyroidectomy because of multiple thyroid nodules that had formed. The medical team advised that there was a risk of thyroid cancer, rated between 10% and 30%, making the removal necessary. The surgery was successful, and I returned home on Sunday. The dressing applied is a transparent sheet with a rolled gauze underneath. However, upon leaving the hospital, I was not given clear guidance regarding how to manage this dressing. My query is: Should I keep the dressing on until my scheduled follow-up appointment at the end of this month, or is it advisable to remove it sooner? If it happens to come off by itself, is that acceptable, or would I need to purchase a new dressing to reapply?
Is My Husband Being Unusual by Seeing His Doctor Again for a Scrotal Examination?
My husband, who is 29 years old, stands at 6 feet 4 inches tall and weighs 225 pounds. He doesn’t smoke and is not on any medication. Last month, he visited his doctor due to a lump he discovered; after examining it, she assured him that it was nothing concerning. Despite her reassurances, he feels the need to schedule a follow-up appointment two months later. I can’t help but wonder if she might think it’s odd for him to come in again just to expose himself. Is this a common concern, or does it seem unusual for him to return for another check-up?
