If I have a mastectomy, could that mean I won't need other treatment after surgery?

In brief: Unlikely

If the breast tumor is a ductal carcinoma or stage 0 breast cancer than you may not need further therapy.
If it is stage 1 or more, you may not need radiation. If it is high risk (lymph nodes involved, triple negative, high oncotype score) you may need chemo and if it is hormone sensitive you may also need a hormone blocker.

In brief: It really depends

Very locally occurring, small non-invasive cancers may be treated definitively with mastectomy but others may require additional treatment, especially if they involved the lymph nodes.
Many times, if there is enough breast tissue, only part of the breast (lumpectomy) needs to be removed and the area is treated with radiation. In may cases, women take anti-estrogens for several years afterwards.

In brief: No

Dependent on the findings at the time of surgery, you may need additional treatment, such as radiotherapy and chemotherapy.

In brief: Yes, maybe

A mastectomy might reduce the need for radiation treatment, but if the cancer is very close to the edges of the removed breast or if there are many lymph nodes involved with cancer, then radiation would still be recommended.
The decision to use chemotherapy or hormonal therapy after mastectomy is strongly influenced by the type of breast cancer so can be complicated.
