A lump of cancerous tissue is typically referred to as a tumor. Tumors can be either benign or malignant. Benign tumors are non-cancerous growths that do not invade nearby tissues or spread to other parts of the body. Malignant tumors, on the other hand, are cancerous growths that have the potential to invade surrounding tissues and metastasize, or spread, to other parts of the body.
The cancer started in the lymph node, but quickly began to spread, since lymph nodes are located throughout the human bodies. Cancerous cells spread throughout a patient's body, destroying the function of healthy cells. If too many cells die like this, organ failure and death result.
Cancerous cells are cells that have undergone genetic mutations that cause them to grow and divide uncontrollably. These cells can form a mass of tissue called a tumor. Tumors can be either benign or malignant. Benign tumors: These tumors are non-cancerous and typically do not invade nearby tissues or spread to other parts of the body. They may grow slowly and often have well-defined borders. Malignant tumors: These tumors are cancerous and can invade nearby tissues and spread to other parts of the body through a process called metastasis. Malignant tumors can be further categorized based on their tissue of origin (e.g., carcinoma, sarcoma, lymphoma, leukemia). So, cancerous cells are the cells that make up malignant tumors, whereas benign tumors are made up of non-cancerous cells. The distinction between benign and malignant tumors is crucial for determining treatment strategies and assessing prognosis.
