Why are tumors encapsulated?

While many benign tumors remain encapsulated, as a result of genetic mutations acquired during tumor progression, others become malignant by developing the skills necessary to degrade and breach the capsule and then spread rapidly through the surrounding tissue.

Is it good for a tumor to be encapsulated?

Significantly better disease-free and actuarial survival times were observed in patients with encapsulated tumors (medians, 9.9 and 18.3 months, respectively), compared with those with nonencapsulated ones (medians, 4.0 and 5.9 months, respectively; P = 0.0001 and 0.001, respectively).

If a malignant tumor remains compact and does not have roots, it is said to be encapsulated. When an otherwise benign tumor is located in a vital area of the brain and interferes with vital functions, it may be considered malignant (even though it contains no cancer cells).

What is a Tumour capsule?

A tumour capsule is a layer of tissue that separates a tumour from the surrounding, normal tissue. A capsule may be present around both benign (non-cancerous) and malignant (cancerous) tumours.
