Cancer is a life-threatening ailment caused by the excessive production and buildup of abnormal or malignant cells in a particular organ of the body which replaces all the healthy and living tissues, eventually leading to organ failure and death. The organ where cancer originates is known as the primary site of cancer. Some cancer cells known as circulating tumour cells have a tendency to spread to other organs via the various blood channels. This procedure is known as metastasis and is responsible for metastatic cancer or s secondary cancer. As per the best cancer specialist doctors in Delhi, the problem is very serious and usually occurs when cancer remains undetected or untreated for a long time.  Metastasis is likely to occur in the lungs, liver, brain and bones.

Various routes through which metastatic cancer can spread:

With the help of the doctors hailing from the best oncology hospital in Delhi, we have enlisted the four main routes through which metastasis can take place.

  • Transcoelomic spread – it refers to the spread of malignant cells from the primary site to the secondary site via peritoneal, pleural, pericardial or subarachnoid penetration.
  • Lymphatic spread – it involves the spread of malignant cells to regional lymph nodes near the primary site, from where it is sent to various other organs. The regional lymph nodes are popularly known as positive nodes. Lymphatic spread is the compost common route of early metastasis for carcinomas.
  • Hematogenous spread – although hematogenous spread mostly occurs in case of sarcomas, it can also be responsible for the metastasis of certain carcinomas. This refers to the spread of the cancerous cells via the veins and majorly depends upon the position of primary cancer.
