Lipoma

Hello, Doctor.
Recently, I discovered an unknown lump on the back of my thigh, approximately 3 centimeters in size.
It does not move, and pressing it firmly causes pain.
I went to the hospital for a consultation, and the doctor diagnosed it as a lipoma through palpation.
He mentioned that it is not dangerous and does not require further attention.
He also said that surgery could be performed to remove it, but there is a chance of recurrence.

1.
I would like to ask if a diagnosis of lipoma can be made solely through palpation in my case.
The doctor was very definitive in his response, stating that lipomas are absolutely benign and will not turn malignant.
However, I found some information online indicating that while most lipomas are benign, the possibility of malignancy cannot be completely ruled out.
2.
Why did the surgical specialist I consulted say it is absolutely benign? He mentioned that he has several lipomas himself and has not addressed them.
Although the doctor told me this, I am still very concerned because I fear there may be exceptions.
3.
If I have a lipoma on my body and choose not to address it, what impact could that have? If it were to become problematic, what warning signs might indicate that? For example, if it causes pain when it shouldn't, does that mean a pathological change has already occurred? I am genuinely worried, and I would appreciate your reassurance.
Thank you.

Hello Kimo: Lipomas are generally benign, and malignant transformation is quite rare.
A tumor that is three centimeters can be considered for surgical removal; if it is larger, there is a higher risk of adhesion and bleeding.
Additionally, you may consider sending it for pathological examination to better differentiate its tissue type and to check for any malignant changes.

When it comes to understanding lipomas, it's essential to grasp both the nature of these growths and the circumstances under which they may require treatment. A lipoma is a benign tumor composed of adipose (fat) tissue. They are typically soft, movable, and painless, and they can occur anywhere on the body. While your doctor has diagnosed your lump as a lipoma based on palpation, it's understandable to have concerns about the accuracy of this diagnosis and the potential for malignancy.

1. Diagnosis of Lipomas: While palpation is a common method for diagnosing lipomas, it is not infallible. In many cases, a healthcare provider can confidently identify a lipoma through physical examination due to its characteristic features. However, if there is any doubt, further diagnostic imaging, such as an ultrasound or MRI, can be employed to confirm the diagnosis and rule out other conditions, including liposarcomas, which are malignant tumors of fatty tissue. It's important to remember that while lipomas are generally benign, there are rare instances where a growth may appear similar but could be malignant. If you have any lingering doubts, seeking a second opinion or requesting imaging studies may provide additional peace of mind.

2. The Nature of Lipomas: Your doctor’s assertion that lipomas are "absolutely benign" is generally accurate, but it’s wise to remain vigilant. While the vast majority of lipomas do not pose health risks, they can sometimes cause discomfort or pain, particularly if they press against nerves or other structures. If a lipoma changes in size, shape, or becomes painful, it is advisable to revisit your healthcare provider for further evaluation. The fact that your doctor has personal experience with lipomas and has chosen not to remove them suggests that he is comfortable with their benign nature, but individual experiences can vary.

3. Impact of Non-Treatment: If a lipoma is confirmed to be benign and is not causing any symptoms, many people choose to leave it untreated. However, if a lipoma grows larger or becomes painful, it may necessitate surgical removal. The decision to remove a lipoma often depends on factors such as its location, size, and whether it causes discomfort. In rare cases, if a lipoma is left untreated and begins to cause significant pain or functional impairment, it may need to be addressed surgically.
4. Signs of Change: You mentioned concerns about pain and whether it could indicate a change in the nature of the lipoma. While lipomas are typically painless, any new pain, rapid growth, or changes in the lump's characteristics should prompt a reevaluation by a healthcare professional. These changes could indicate that the growth is not a typical lipoma and may warrant further investigation.

In conclusion, while your doctor’s diagnosis of a lipoma based on palpation is likely correct, it is always prudent to stay informed and proactive about your health. If you have persistent concerns, consider discussing them with your healthcare provider or seeking a second opinion. Understanding your body and advocating for your health is crucial, and you deserve to feel confident in your diagnosis and treatment options.
