What happens when a cell turns cancerous?

Cancer cells can break away from the original tumor and travel through the blood or lymph system to distant locations in the body, where they exit the vessels to form additional tumors. This is called metastasis. Cancer is a disease caused when cells divide uncontrollably and spread into surrounding tissues.

How quickly does a cancerous lump grow?

Scientists have found that for most breast and bowel cancers, the tumours begin to grow around ten years before they’re detected. And for prostate cancer, tumours can be many decades old. “They’ve estimated that one tumour was 40 years old. Sometimes the growth can be really slow,” says Graham.

Does carcinoma mean malignant?

Carcinoma is a malignancy that begins in the skin or in tissues that line or cover internal organs. Sarcoma is a malignancy that begins in bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue.

Do cancerous lumps appear suddenly?

Bumps that are cancerous are typically large, hard, painless to the touch and appear spontaneously. The mass will grow in size steadily over the weeks and months.

What are the symptoms of cancerous plasma cells?

As the cancerous plasma cells fill the bone marrow, you are not able to make enough normal blood cells. This can lead to anaemia, bleeding problems and infections. Other symptoms include bone pain, breaks (fractures) due to bone damage, and kidney damage.

What is the difference between normal and cancer cells?

(Normal cells are well differentiated and cancer cells are not.) Because tumors often consist of multiple cell types, the pathologist assigns two values between 1 and 5: the first to the predominant cell type, and the second to the next-most-prevalent cell type (see Figure 1).

What causes plasmapheres to become cancerous?

Plasma cells develop from small white cells called B lymphocytes. It is thought that as B lymphocytes develop into plasma cells, mistakes occur in the process which copies genetic material, leading to the cell becoming cancerous. The cancerous cell multiplies, leading to the development of myeloma, as described above.

What does it mean when cancer is suspicious but not diagnosed?

Sometimes this finding is reported as “suggestive of” or “suspicious for” cancer but not diagnostic of cancer. This frustratingly equivocal diagnosis usually means that the pathologist looked at the tissue on the slides and saw cells that were not typical, but they were not abnormal enough to classify as cancer (see “What makes it cancer?”).
