Final answer:
An immovable lump could be a sign of malignancy and warrants medical evaluation. Benign tumors, such as fibroids or moles, are not life-threatening and may only be removed for comfort. Accurate diagnosis and treatment often require a biopsy or imaging.
Step-by-step explanation:
When considering a lump that is immovable/fixed, it is important to understand the characteristics of both benign and malignant tumors. Benign tumors, such as breast and uterine fibroids or moles, generally stop growing and are not life-threatening. They might be removed for comfort or to eliminate the risk of them becoming cancerous. However a fixed lump could be cause for concern as immobility is often associated with malignant tumors.
Malignancies are characterized by invasive growth, the potential to spread to other parts of the body (metastasize), and may require more extensive treatment. If you discover a lump that is immovable it is crucial to consult with a healthcare provider for a proper diagnosis and treatment plan. Only a medical evaluation, which could include a biopsy or imaging, can truly determine if a lump is benign or malignant. Therefore, while not all immovable lumps are malignant, their presence warrants prompt medical attention to rule out the possibility of cancer.
