DT Calculator Free app for iPhone and iPad

DT Calculator, jointly developed with a medical doctor, is an application to calculate a tumor doubling time, which is an indication of a growth speed of a cancer.
The tumor doubling time is the putative period of time required for a quantity of cancer cells to double. Namely, the shorter doubling time suggests the faster proliferation of the cancer cells. On the contrary, the longer doubling time suggests the slower proliferation.
By entering two examination dates and sizes of the tumor (the maximum diameter), you can calculate the doubling time.

DT Calculator Free have only a function to calculate the tumor volume doubling time by using maximum diameter, which can be applied to many kinds of solid cancers.
DT Calculator and DT Calculator Lite have additional functions such as calculating tumor marker doubling time in addition to volume doubling time, sending the results through e-mail and estimating values on the next examination.

[Usage]
Calculating Tumor Doubling Time.
1. Select a maximum diameter at First Screen.
2. Touch [Done] button to move to Input Screen.
3. Input two dates and values of maximum diameter.
4. Touch [Next] button and input all the data required on the Screen.
5. Touch [Calc] button to move to Result Screen, where you can see the calculation result.

[Disclaimer]
Please use this application as a guide to obtain a rough image of the growth speed of the cancer, and use in consultation with a specialist, if you use this application at the actual clinical settings.
