As an expert in the field of medical oncology, I can provide you with an informative response regarding the shape of tumors. Tumors can be broadly classified into two main categories: benign and malignant. The shape of a tumor is influenced by its nature, growth pattern, and the surrounding tissue environment.
Benign Tumors: These are non-cancerous growths that do not invade nearby tissues or spread to other parts of the body. Benign tumors are often round in shape and are encapsulated by a layer of fibrous connective tissue. This encapsulation helps to demarcate the tumor from the surrounding healthy tissue. The growth of benign tumors is typically slow and they do not pose a significant threat to life, although they can sometimes cause problems if they press on vital structures or if they grow large enough to disrupt normal bodily functions.
Malignant Tumors: Also known as cancers, these are growths that can invade and destroy nearby tissues and organs. They can also spread to other parts of the body through the bloodstream or lymphatic system, a process known as metastasis. Malignant tumors are often irregularly shaped and lack a clear border, which makes them more difficult to remove surgically. They are characterized by rapid and uncontrolled growth, which can lead to the destruction of normal tissue. The vascular nature of malignant tumors allows them to grow quickly by establishing a blood supply to support their growth.
The description you provided mentions an upper tumor that is benign and non-invasive, which aligns with the typical characteristics of benign tumors. The lower tumor, described as malignant, fits the profile of cancerous growths that are irregular, vascular, and invasive.
It's important to note that while the shape of a tumor can provide some clues about its nature, a definitive diagnosis requires a biopsy, where a small sample of the tumor is examined under a microscope to determine its cellular composition and growth characteristics. Imaging studies such as CT scans, MRI, and PET scans can also be used to visualize the tumor and assess its size, shape, and location.
In conclusion, the shape of a tumor is a critical factor in understanding its potential impact on the body. Benign tumors tend to be round and encapsulated, while malignant tumors are irregularly shaped and invasive. Understanding these differences is crucial for developing an appropriate treatment plan and predicting the prognosis of the patient.

The upper tumor is a benign tumor that is non-invasive. Benign tumors are usually round in shape and encapsulated by fibrous connective tissue. The lower picture depicts a malignant tumour. It is irregularly shaped, vascular, and it is invasive, crossing the basement membrane.
