# breastcanc-ultrasound-class

## Background

Cancer is the second leading cause of death worldwide, according to _IHME - Global Burden of Disease_, with 10.7 mln casualties in 2019. 

![total_deaths](./annual-number-of-deaths-by-cause.png)

Amongst the various types of cancer, a huge role is played by breast cancer, which stands in 4th position among the deadliest tumors, with more than 700.000 deaths during 2019 (_IHME - Global Burden of Disease_).

Moreover, breast cancer has the highest share of number of cases/100 people worldwide (0.23 cases/100 people; _IHME - Global Burden of Disease_), as shown in [table1](#table-1)
:

### Table 1

| Type of Cancer                       | Cases per 100 people                      |
|--------------------------------------|-------------------------------------------|
| Breast Cancer                        | 0.23%                                     |
| Colon and Rectum Cancer              | 0.14                                      |
| Prostate cancer                      | 0.13                                      |
| Bladder Cancer                       | 0.034                                     |
| Stomach Cancer                       | 0.033                                     |

In this sense, it is more than vital to put intense effort into precision medicine and diagnostic tools for what concerns breast cancer: part of this effort should involve making curated dataset of diagnostic images available to the large public.
