- Looking at Figure 1, what did Romansik et al. (2007) find regarding the relationship between the mitotic index and tumor grades. Explain their findings in your own words. Use specific details from Figure 1. The research paper is here: https://journals.sagepub.com/doi/10.1354/vp.44-3-335Imagine you have used cBioportal and breast cancer patient datasets and identified a cancer-associated mutation in a particular protein. What would you do next to understand whether that mutation contributes to tumor progression (include experimental approach)?Which of the following statements are correct about tumor cell masses (select all that apply)? A. Stromal cells of tumor masses are generally just contaminants and play no role in tumor progression B. Most stromal cells are of mesenchymal origin C. Fibroblasts, macrophages and lymphocytes are commonly found in the stroma of tumor masses D. In Hodgkin's Lymphoma, the majority of cells in the tumor mass are neoplastic E. In carcinomas, neoplastic and stromal cells are present at similar numbers

- Discussion: (1 or 2 paragraphs with your own opinion like how Circulating Tumor DNA as Biomarkers for Cancer Detection technology can be early detector of cancer)With regard to cancer cells, which of the following are true? A. Cancer cells are clonal, meaning that they are derived from many different cells that all underwent the same clonal mutation. Cells usually accumulate many mutations over time, and this results in cancerous growth. B. Almost all cancers are caused by oncogenic viruses. no Benign tumors are dangerous because they can easily invade surrounding tissue and spread to other locations in the body. DE. Cancer cells are unable to control their division.Which of the following statements are correct about tumors and metastasis (select all that apply)? A. The majority of cancer deaths are due to primary tumor B. Loss of basement membrane by tumor mass is strong predictor of metastasis potential C.

If the probability of develop resistance to drug A is 1/10 and for Drug B is also 1/10, then the probility of developing resistance to Drug A and B combination therapy is 1/20. D.
