Patients must have a life expectancy >= 16 weeks
Breast cancer with chest wall disease that is at least 2 cm in size at the greatest dimension
Patients will be eligible for this trial regardless of number of lines of therapy and after adjuvant chemotherapy with recurrence on the chest wall
Patients with hormone receptor positive disease who discontinue endocrine therapy two weeks prior to initiating study treatment are eligible
Body mass index (BMI): 15 to 50 at the time of consent

Postmenopausal or evidence of non-childbearing status for women of childbearing potential: negative urine or serum pregnancy test within 28 days of initiating study treatment and confirmed prior to treatment on day 1 and willingness to use effective contraception during study treatment and for at least 30 days after last dose of study drug. Postmenopausal is defined as:

Amenorrhea for 1 year or more following cessation of exogenous hormonal treatments
Luteinizing hormone (LH) and follicle stimulating hormone (FSH) levels in the post menopausal range for women under 50
Radiation-induced oophorectomy with last menses > 1 year ago
Chemotherapy-induced menopause with > 1 year interval since last menses
Surgical sterilization (bilateral oophorectomy or hysterectomy)

Exclusion Criteria:

As judged by the investigator, any evidence of non-compliance which in the investigator's opinion makes it undesirable for the patient to participate in the trial
Patients with rapidly progressing disease
Metastatic disease should not be progressing so as to require systemic treatment within 4 weeks of enrollment based on clinical assessment by the investigator
Metastatic disease should not be progressing so as to require palliative treatment within 4 weeks of enrollment based on clinical assessment by the investigator
Other malignancy unless curatively treated with no evidence of disease for >= 5 years except: adequately treated non-melanoma skin cancer, curatively treated in situ cancer of the cervix, ductal carcinoma in situ (DCIS), stage 1, grade 1 endometrial carcinoma
Resting electrocardiogram (EKG) indicating uncontrolled, potentially reversible cardiac conditions, as judged by the investigator (e.g. unstable ischemia, uncontrolled symptomatic arrhythmia, congestive heart failure, corrected QT interval by Fridericia [QTcF] prolongation > 500 ms, electrolyte disturbances, etc.), or patients with congenital long QT syndrome
Persistent toxicities caused by previous cancer therapy >= grade 2, excluding alopecia and neuropathy
Patients with current or previous diagnosis of myelodysplastic syndrome/acute myeloid leukemia or with features suggestive of myelodysplastic syndrome (MDS)/acute myeloid leukemia (AML)
Patients with symptomatic uncontrolled brain metastases or spinal cord metastases. A scan to confirm the absence of brain metastases is not required. The patient can receive a stable dose of corticosteroids before and during the study as long as these were started at least 4 weeks prior to treatment. Patients with spinal cord compression unless considered to have received definitive treatment for this and evidence of clinically stable disease for 28 days
Patients considered a poor medical risk due to a serious, uncontrolled medical disorder, non-malignant systemic disease or active, uncontrolled infection. Examples include, but are not limited to, uncontrolled ventricular arrhythmia, recent (within 3 months) myocardial infarction, uncontrolled major seizure disorder, unstable spinal cord compression, superior vena cava syndrome, extensive interstitial bilateral lung disease on high resolution computed tomography (HRCT) scan or any psychiatric disorder that prohibits obtaining informed consent
Patients unable to swallow orally administered medication and patients with gastrointestinal disorders likely to interfere with absorption of the study medication
Immunocompromised patients, e.g., patients who are known to be serologically positive for human immunodeficiency virus (HIV)
Any previous treatment with PARP inhibitor, including olaparib
Subjects with a known hypersensitivity to olaparib or any of the excipients of the product
Patients with a known hypersensitivity to hyperthermia
Patients receiving any systemic chemotherapy or radiotherapy (except for palliative reasons) within 3 weeks prior to study treatment
Concomitant use of known strong CYP3A inhibitors (e.g. itraconazole, telithromycin, clarithromycin, protease inhibitors boosted with ritonavir or cobicistat, indinavir, saquinavir, nelfinavir, boceprevir, telaprevir) or moderate CYP3A inhibitors (e.g. ciprofloxacin, erythromycin, diltiazem, fluconazole, verapamil). The required washout period prior to starting olaparib is 2 weeks
Concomitant use of known strong CYP3A inducers (eg. phenobarbital, enzalutamide, phenytoin, rifampicin, rifabutin, rifapentine, carbamazepine, nevirapine and St John's wort) or moderate CYP3A inducers (eg. bosentan, efavirenz, modafinil). The required washout period prior to starting olaparib is 5 weeks for enzalutamide or phenobarbital and 3 weeks for other agents
Major surgery within 2 weeks of starting study treatment and patients must have recovered from any effects of surgery
Patients with known active hepatitis B or C
Whole blood transfusions in the last 120 days prior to entry to the study (packed red blood cells and platelet transfusions are acceptable outside of 28 days prior to enrollment)

No radiotherapy, treatment with cytotoxic agents, biologic agents within 3 weeks prior to beginning treatment on this study. Patients must have recovered from the acute toxicities of any prior treatment with cytotoxic drugs to =< grade 1 (allowance for grade 2 alopecia and neuropathy) in order to be eligible. Patients who underwent post-mastectomy radiation will not be excluded from this study
