Cell differentiation is not a known mechanism of cancer metastasis. Therefore, the correct answer is option (d) Cell differentiation.

Tamoxifen is a drug commonly used in the treatment of breast cancer, particularly those that express the estrogen receptor. Therefore, the correct answer is option (a) Breast cancer.

The cancer stem cell hypothesis suggests that only a small subset of cancer cells possess tumorigenic potential, and that these cells are responsible for tumour growth and metastasis. Therefore, the correct answer is an option (b) Only a small subset of cancer cells possess tumorigenic potential.

Melanoma is a type of skin cancer that arises from the pigment-producing cells in the skin. Therefore, the correct answer is option (c) Melanoma.

The Warburg effect refers to the increased reliance of cancer cells on glycolysis for energy production, even in the presence of oxygen. Therefore, the correct answer is an option (b) Increased glycolysis in cancer cells.

Blood type is not a known risk factor for cancer. Therefore, the correct answer is option (d) Blood type.

The BRCA1 gene encodes a protein that is involved in DNA repair. Therefore, the correct answer is option (b) DNA repair.

Resistance to cell death signals is a hallmark of cancer cells, as they evade apoptosis and continue to proliferate. Therefore, the correct answer is option (c) Resistance to cell death signals.

The p53 tumour suppressor gene functions to promote DNA repair and inhibit cell proliferation. Therefore, the correct answer is an option (d) Promote DNA repair.

Helicase is the enzyme responsible for the unwinding of the DNA double helix during replication. Therefore, the correct answer is option (b) Helicase.
