I have a metastasis to my lung that has grown from 6 mm in June to 9 mm in September, over a period of exactly 99 days. I got online and put the information into Doubling Time calculators, and the doubling time is about 53-56 days.
Question: is this rate of growth considered aggressive cancer? I looked on the internet but wasn't able to find an answer to this question. I also know that aggressive cancer is typified by other characteristics, such as how well-defined the cancer cells are, but for my basic purposes, I was wondering what the Doubling Time of my cancer indicates.
Background: I had a surgery in January 2015 to remove a metastatic tumor from the lower left lobe, near the wall of the lung, and my surgeon said he thought he had gotten all the cancer. The scan in June, however, showed the new tumor more in the center of my lung. I had a biopsy, which showed the tumor positive for Esophageal Cancer, which was my initial cancer. So:
- 2007: Initial Esophageal Cancer
- 2014: Metastasis to lower left lobe, surgically removed
- 2015: Metastasis to center left lobe
Thank you in advance for any help or comments on this.
