Tumor stroma and extracellular matrix in hypoxia. Tumor hypoxia is the situation where tumor cells have been deprived of oxygen.As a tumor grows, it rapidly outgrows its blood supply, leaving portions of the tumor with regions where the oxygen concentration is significantly lower than in healthy tissues.
[28] [29] Although benign tumors generally grow slowly, cases of fast-growing benign tumors have also been documented. [30] Some malignant tumors are mostly non-metastatic such as in the case of basal-cell carcinoma. [31] CT and chest radiography can be a useful diagnostic exam in visualizing a benign tumor and differentiating it from a ...

The treatment of invasive carcinoma NST is often similar to management plans for other invasive breast carcinomas. The treatment options offered to an individual patient are determined by the form, stage and location of the cancer, and also by the age, history of prior disease and general health of the patient.
Disseminating cancer cells can proliferate or become dormant depending on the microenvironment and factors such as the ERK/p38 ratio. Dormancy is a stage in cancer progression where the cells cease dividing but survive in a quiescent state while waiting for appropriate environmental conditions to begin proliferation again. [ 1 ]
The enzyme telomerase is used to extend the cancer cell's life span. While the telomeres of most cells shorten after each division, eventually causing the cell to die, telomerase extends the cell's telomeres. This is a major reason that cancer cells can accumulate over time, creating tumors.
