It's more than 2 group so it's defently not T test. I will go with ANOVA but not sure one or 2 way.

you have to compare 3 groups: 30, 30 and 15 and
2 qualities (means) -- efficacy of surgical interventions for breast cancer AND the quality of life, measured on a ten point scale. So, 2 way anova. If they mean ONE quality by stating: "efficacy of surgical interventions for breast cancer, the quality of life, measured on a ten point scale", then it is one way anova.

Two way Anova tests two variables AND the interaction between them ( in 3 groups or more)
here they are testing three groups and the relations between their surgeries and quality of life
