What is stage 3D cancer?

Stage 3D cancer, usually refers to the staging system used for certain types of cancer, such as lung cancer or bladder cancer, under the Tumor Node Metastasis (TNM) staging system. Here's an explanation:

Lung cancer:

- Stage 3D non-small cell lung cancer (NSCLC) indicates advanced localized disease.

- The tumor (T) is usually large and may have invaded nearby structures like the chest wall, diaphragm, or mediastinal organs.

- There are no distant metastases (M), meaning the cancer has not spread to other organs outside the chest.

- Lymph nodes (N) in the mediastinum or near the affected lung are involved with cancer.

Bladder cancer:

- Stage 3D bladder cancer is an advanced stage.

- The tumor has invaded the muscular layer of the bladder (T3).

- There may be a single or multiple tumors within the bladder.

- Lymph nodes (N) near the bladder are affected by the cancer.

- There is no distant metastases (M0) to other organs.

It's important to note that the specific staging criteria may vary depending on the type of cancer. Therefore, it's essential to consult with a healthcare professional for accurate and personalized information regarding the stage of a particular cancer.
