Short answer

Answer: In situ

Step-by-step solution

Understanding Tumor Classification - Tis

Tis or "Tumor in situ" is a term that refers to tumor cells that have not invaded beyond the layer of cells from which they originated. This means that the cancer cells have remained confined to the site where they first formed and have not spread to nearby tissues or distant body parts.

Evaluate each option

Now that we understand what the Tis classification means, let us look at each option and see if it fits with the Tis classification: A. That cannot be assessed: This does not describe the Tis classification, as the primary tumor has already been given a classification of Tis. B. That is in situ: This answer matches our understanding of the Tis classification. C. With increasing lymph node involvement: Although a Tis tumor may later change and involve nearby lymph nodes, the Tis classification itself does not imply increasing lymph node involvement. D. With distant metastasis: This option contradicts the definition of Tis tumors, as they have not spread to distant body parts.

Choose the correct answer

Based on our understanding of the Tis classification and the given options, we can choose the correct answer: Option B: That is in situ.
