Groin Lymph Nodes: When to Seek Medical Attention - Oncology

Inguinal lymph nodes


Hello, Doctor.
I apologize for reaching out while I am currently abroad, and I plan to return to Taiwan in three months.
I would like to hear your opinion on whether I should return to Taiwan for medical evaluation at this time.
Since December of last year, I have had a hard lump under the skin at the root of my left thigh.
It is spherical, slightly painful when pressed firmly, and movable.
In January of this year, I visited a dermatologist in Taiwan, who believed it to be a lipoma and suggested monitoring it.
I then returned abroad.
However, starting around February or March of this year, I noticed hard lumps developing under the skin in both groin areas, which are also spherical and movable, but I have not experienced any other unusual symptoms and continued to monitor them.
By May, I began to feel a sensation of heat and chills daily, although my body temperature has not shown fever, measuring around 36.8°C (previously my normal temperature was around 36.3-36.4°C).
I have been having trouble sleeping, waking up at night, but I do not experience night sweats, and my weight has remained stable and normal.
I have had an ultrasound performed by a surgeon abroad, who confirmed the presence of multiple lymph nodes, with the largest measuring 1.3 cm x 0.7 cm x 0.6 cm.
I am very concerned about the possibility of lymphoma or lymphatic cancer.
Do you have any recommendations, Doctor? Thank you!

Thank you.

When it comes to lymph nodes, particularly in the groin area, it is essential to understand their significance and when to seek medical attention. Based on your description, you have experienced the development of multiple hard lumps in your groin, which have been assessed by a dermatologist as likely being lipomas. However, the presence of enlarged lymph nodes, especially those that are firm, painful, or have changed in size or number, warrants further evaluation.

Lymph nodes are part of the lymphatic system, which plays a crucial role in the immune response. They can become enlarged due to various reasons, including infections, inflammatory conditions, or malignancies such as lymphoma. In your case, the fact that you have multiple lymph nodes measuring up to 1.3 cm in size raises some concerns, especially given the accompanying symptoms of low-grade fever, chills, and sleep disturbances.

Here are some key points to consider regarding your situation:
1. Characteristics of Lymph Nodes: Lymph nodes that are mobile, firm, and non-tender are often benign, but any changes in size, consistency, or associated symptoms should be taken seriously. The presence of multiple enlarged lymph nodes, especially if they are new or have changed, can be indicative of an underlying issue that needs further investigation.

2. Symptoms to Monitor: You mentioned experiencing a low-grade fever and feeling unwell, which can be signs of an underlying infection or other systemic issues. While a stable weight and absence of night sweats are reassuring, the combination of these symptoms with the enlarged lymph nodes should prompt further evaluation.

3. When to Seek Medical Attention: Given your current situation, it would be advisable to consult a healthcare professional sooner rather than later. If you are experiencing persistent symptoms or if the lymph nodes continue to enlarge, it may be necessary to return to Taiwan for a thorough evaluation, including imaging studies (like an ultrasound or CT scan) and possibly a biopsy to rule out malignancy.

4. Potential Diagnostic Steps: If you decide to seek medical attention, the healthcare provider may recommend blood tests, imaging studies, and possibly a biopsy of the lymph nodes to determine their nature. This is crucial in distinguishing between benign conditions (like infections or reactive lymphadenopathy) and more serious conditions (like lymphoma).

5. Follow-Up Care: If you are unable to return to Taiwan immediately, consider seeking care in your current location. A local healthcare provider can perform the necessary evaluations and provide guidance based on your symptoms and the findings from the ultrasound.

In conclusion, while the initial assessment by the dermatologist suggested a benign condition, the development of multiple enlarged lymph nodes and accompanying symptoms necessitates further investigation. It is essential to prioritize your health and seek medical attention to ensure that any potential issues are addressed promptly. If you feel that your symptoms are worsening or if you have significant concerns, returning to Taiwan for a thorough evaluation may be the best course of action.
