Will the boundaries of a benign tumor be unclear?

Tumor is a very harmful disease in people's lives. It is fatal to the body and often causes death and serious physical damage to patients. Tumors are divided into two types: benign and malignant. Among them, benign tumors are less harmful and can be treated. But will the boundaries of benign tumors be unclear? Then we need to look at the differences between benign tumors and malignant tumors. Let’s take a look at the explanation below.

A tumor is a new growth that is not normal tissue. Tumors can be divided into two categories: benign and malignant, depending on their growth characteristics and their effects and harms to the human body. Tumors can occur in almost any part or organ of the human body. What people call cancer in their daily life is a malignant tumor. However, some benign tumors can also cause great harm to the human body because they grow around important organs.

The main differences between benign tumors and malignant tumors are as follows.

1. Growth pattern: Benign tumors grow in an expansive manner, with clear boundaries with normal tissues, and most of them have capsules formed around the tumors; while malignant tumors grow in an invasive and destructive manner, with unclear boundaries with the surrounding normal tissues and no obvious capsule formation.

2. Growth rate: Benign tumors usually grow slowly; malignant tumors generally grow rapidly, but may become necrotic and ulcerated because the growing tumor does not receive sufficient blood supply.

3. Recurrence: Benign tumors usually do not recur after surgical resection; malignant tumors are prone to recurrence after surgical resection.

4. Metastasis: Benign tumors usually do not metastasize; malignant tumors can metastasize to other parts of the body through the lymphatic vessels, blood vessels, etc.

5. Degree of differentiation and tissue structure: The differentiated morphology of benign tumor cells is similar to that of normal tissue, and the tissue structure is also similar to the original normal tissue; the degree of differentiation of malignant tumor cells is relatively poor, often showing abnormal morphology to varying degrees, and the tissue structure is also significantly different from the original normal tissue.

6. Impact on the human body and organ functions: Most benign tumors have little effect on organ functions. Larger benign tumors may have a certain degree of compression on tissues and organs, but most do not affect function. However, benign tumors growing in special parts, such as around the spinal cord or inside the skull, can have serious effects.
