Tumors of the Oral Cavity

Tumours are in general uncontrolled multiplication of cells which result in a tumour. The origin or the tumours can be any of the four mentioned below like Epithelial, Connective tissue, Muscle tissue or Nerve tissue and the tumours can be Benign or Malignant based on various factors. It is important to identify the tumours in their earlier stages with the help of diagnostic tests like Biopsy and some specific tests.

Benign tumours are usually not harmful as they do not invade adjacent tissues and are also not metastatic restricting their growth to only one place. The Benign tumours can be removed or excised easily as they do not invade into adjacent tissues and can be differentiated from other cells. There are very low chances of recurrence in benign tumours. In case of Malignant tumours the uncontrolled multiplication of the cells usually invade the adjacent tissues and the borders of the tumours are not well differentiated making it difficult to completely excise the tumours. There are high chances of metastasis through various routes and the lesion can invade any region of the body depending on the type of tumour it originated from

The tumors of the oral cavity are classified into types based on their origin, the Tumors are classified into 4 types like:

  1. Tumors of Epithelial origin.
  2. Tumors of Connective tissue origin.
  3. Tumors of Muscle Tissue Origin.
  4. Tumors of Nerve Tissue Origin.

These Tumours are again divided into types each based on the stage of the Tumor:

1. Tumors of Epithelial origin:

  • Benign Tumors of Epithelial origin.
  • Pre malignant Lesions/Conditions of Epithelial origin.
  • Malignant Tumors of Epithelial origin.
2. Tumors of Connective Tissue origin.
  • Benign Tumors of Connective tissue origin.
  • Malignant Tumors of Connective Tissue origin.
3. Tumors of Muscle Tissue Origin.
  • Benign tumors of Muscle tissue origin.
  • Malignant tumors of Muscle tissue origin.
4. Tumors of Nerve Tissue Origin.
  • Benign Tumors of Nerve tissue origin.
  • Malignant tumors or Nerve tissue origin.
 Based on the origin of the tumours there are differences in routes of metastasis and the various parts of the body which they might spread to. It is important to identify and diagnose the tumors  in their early stages to make sure that the treatment is planned accordingly before any metastasis of the lesion.
