Tumour
Tumours are excrescences due to abnormal cell proliferation. Two types of tumour can be distinguished: benign tumours and malignant tumours.
Benign tumours are tumours without serious implications. In some cases, surgical ablation may be necessary and sufficient. In other cases, simple medical follow-up is ensured to monitor the progression of the tumour.
Malignant tumours are abnormal masses of cancerous cells. Malignant tumours are capable of invading and destroying adjacent tissues. They can also spread. Their cellular structures differ from those of the tissues from which they develop and which they invade.
All tumours must be taken seriously and be correctly identified by a specialist.
