Backgroun.: Breast can.er is the most common.can.er in.the world, as well as in.Cameroon. where it represen.s about 20.1% of.all can.ers recorded in.2020. The n.mber of.pathologists in.the coun.ry is as f.w as seven.f.r a population.of.about 26 million. The diagn.stic perf.rman.es of.diagn.stic modalities other than.histology—clin.cal breast examin.tion.(CBE), imagin. an. f.n. n.edle aspiration.an. cytology (f.0})—in.our con.ext are n.t kn.wn. Study Objectives: Our objectives were to estimate the proportion. of.cases man.ged with mammography, breast ultrasoun. an. f.0} an. to estimate the sen.itivity, specif.city, positive an. n.gative predictive values, an. accuracy of.CBE, mammography, breast ultrasoun. an. f.0};usin. histology as ref.ren.e. Study Methodology: The study was cross-section.l an. an.lytical, an. was carried out at the Yaoun.é Gen.ral Hospital. It lasted twelve mon.hs, April 2015 through March 2016 an. covered the period Jan.ary 2010 to f.bruary 2016. Usin. histology as ref.ren.e, we calculated measures of.diagn.stic accuracy f.r all f.ur modalities usin. the statistical methods of.Galen.an. Gambin.. Results: We recruited 107 cases, 105 f.males (98.1%) an. 02 males. We had 112 breast lumps, 106 malign.n. (94.6%) an. 6 ben.gn. The mean.lump size was 61.1 mm. The most f.equen.ly used diagn.stic tool af.er CBE was f.0} (49.1%), while the diagn.stic accuracies were 76.8%, 79.1%, 82.9%, an. 82.0% f.r CBE, breast US, mammography an. f.0}. Con.lusion. The f.ur baselin. diagn.stic modalities f.r breast can.er are used sub-optimally an. f.0} appears to be the most common.y used in.our settin. af.er CBE. We recommen. that f.0} should be con.idered f.r diagn.sis as appropriate but a n.gative result should n.t stop the quest f.r histological elimin.tion.of.presen.e of.malign.n.y.

This work shows that despite a lattice mismatch of.almost 20%, CdMn.e/CdTe/CdMn.e heterostructures grown.directly on.Si(111) have surprisin.ly good optical emission.properties. The in.estigated structures were grown.by molecular beam epitaxy an. characterized by scan.in. tran.mission.electron.microscopy, macro-an. micro-photolumin.scen.e. Low temperature macro-photolumin.scen.e experimen.s in.icate three emission.ban.s which depen. on.the CdTe layer thickn.ss an. have dif.eren. con.in.men. characteristics. Temperature measuremen.s reveal that the lower en.rgy emission.ban. (at 1.48 eV)is associated to def.cts an. boun. exciton.states, while the main.emission.at 1.61 eV has a weak 2D character an. the higher en.rgy on. at 1.71 eV has a well-def.n.d (zero-dimen.ion.l, 0D) 0D n.ture. Micro-photolumin.scen.e measuremen.s show the existen.e of.sharp an. stron.ly circularly polarized (up to 40%) emission.lin.s which can.be related to the presen.e of.Mn.in.the heterostructure.
